An anonymous reader shared this report from the Washington Post: Facebook's loosening of its content moderation standards early this year got lots of attention and criticism. But a new study suggests that it might matter less what is taken down than when. The research finds that Facebook posts removed for violating standards or other reasons have already been seen by at least three-quarters of the people who would be predicted to ever see them.

"Content takedowns on Facebook just don't matter all that much, because of how long they take to happen," said Laura Edelson, an assistant professor of computer science at Northeastern University and the lead author of the paper in the Journal of Online Trust and Safety. Social media platforms generally measure how many bad posts they have taken down as an indication of their efforts to suppress harmful or illegal material. The researchers advocate a new metric: How many people were prevented from seeing a bad post by Facebook taking it down...?

"Removed content we saw was mostly garden-variety spam — ads for financial scams, [multilevel marketing] schemes, that kind of thing," Edelson said... The new research is a reminder that platforms inadvertently host lots of posts that everyone agrees are bad.

Apple was fined 500 million euros ($570 million) on Wednesday and Meta 200 million euros, as European Union antitrust regulators handed out the first sanctions under landmark legislation aimed at curbing the power of Big Tech. From a report: The EU fines could stoke tensions with U.S. President Donald Trump who has threatened to levy tariffs against countries that penalise U.S. companies. WSJ adds more details: The commission also issued cease-and-desist orders that could have a bigger impact than the fines. One order targets Apple's App Store and the other takes aim at Meta's use of personalized ads -- important revenue streams for each company.

[...] The EU's action against Meta focuses on the company's effort to get users to agree to seeing personalized ads on Instagram and Facebook -- its main source of revenue. The commission ordered Meta to stop requiring users to either agree to those ads or pay for a subscription. It said it was still evaluating whether a "less-personalized ads" option that Meta introduced last fall complies with that order, raising the specter of further changes.

The Apple case deals with the company's App Store rules. The commission said Apple had failed to comply with an obligation to allow app developers to inform customers, free of charge, of alternative ways to purchase digital products.

An anonymous reader shares a report: Kevin Systrom, the co-founder of Instagram, testified on Tuesday in a landmark federal antitrust trial that he left Meta in 2018 because his company was denied resources. The government has argued that Meta purchased Instagram in 2012 as part of a "buy-or-bury strategy" to illegally cement its social media monopoly by killing off its rivals. Last week, current and former Meta executives testified that the social media giant, formerly known as Facebook, used its deep pockets to invest in Instagram after its purchase.

In testimony at the U.S. District Court of the District of Columbia, Mr. Systrom painted a different picture, saying he left Meta because Mark Zuckerberg, the chief executive, wasn't investing enough. At that time, Instagram had grown to 1 billion users, about 40 percent of Facebook's size, yet the photo-sharing app had only 1,000 employees compared to 35,000 employees at Facebook, he said. "We were by far the fastest growing team. We produced the most revenue and relative to what we should have been at the time, I felt like we should have been much larger," said Mr. Systrom, who is expected to testify for six hours.

Mr. Systrom said he found the decisions baffling. When asked by an F.T.C. lawyer why Mr. Zuckerberg might have decided to give Instagram fewer resources, Mr. Systrom said it was a consistent pattern during his tenure at Meta. "Mark was not investing in Instagram because he believed we were a threat to their growth," he said, referring to Mr. Zuckerberg's prioritization of Facebook.

Abstract of a paper on National Bureau of Economic Research: We estimate the effect of social media deactivation on users' emotional state in two large randomized experiments before the 2020 U.S. election. People who deactivated Facebook for the six weeks before the election reported a 0.060 standard deviation improvement in an index of happiness, depression, and anxiety, relative to controls who deactivated for just the first of those six weeks. People who deactivated Instagram for those six weeks reported a 0.041 standard deviation improvement relative to controls. Exploratory analysis suggests the Facebook effect is driven by people over 35, while the Instagram effect is driven by women under 25.

"Russia is automating the spread of false information to fool AI chatbots," reports the Washington Post. (When researchers checked 10 chatbots, a third of the responses repeated false pro-Russia messaging.)

The Post argues that this tactic offers "a playbook to other bad actors on how to game AI to push content meant to inflame, influence and obfuscate instead of inform," and calls it "a fundamental weakness of the AI industry." Chatbot answers depend on the data fed into them. A guiding principle is that the more the chatbots read, the more informed their answers will be, which is why the industry is ravenous for content. But mass quantities of well-aimed chaff can skew the answers on specific topics. For Russia, that is the war in Ukraine. But for a politician, it could be an opponent; for a commercial firm, it could be a competitor. "Most chatbots struggle with disinformation," said Giada Pistilli, principal ethicist at open-source AI platform Hugging Face. "They have basic safeguards against harmful content but can't reliably spot sophisticated propaganda, [and] the problem gets worse with search-augmented systems that prioritize recent information."

Early commercial attempts to manipulate chat results also are gathering steam, with some of the same digital marketers who once offered search engine optimization — or SEO — for higher Google rankings now trying to pump up mentions by AI chatbots through "generative engine optimization" — or GEO.
Our current situation "plays into the hands of those with the most means and the most to gain: for now, experts say, that is national governments with expertise in spreading propaganda." Russia and, to a lesser extent, China have been exploiting that advantage by flooding the zone with fables. But anyone could do the same, burning up far fewer resources than previous troll farm operations... In a twist that befuddled researchers for a year, almost no human beings visit the sites, which are hard to browse or search. Instead, their content is aimed at crawlers, the software programs that scour the web and bring back content for search engines and large language models. While those AI ventures are trained on a variety of datasets, an increasing number are offering chatbots that search the current web. Those are more likely to pick up something false if it is recent, and even more so if hundreds of pages on the web are saying much the same thing...

The gambit is even more effective because the Russian operation managed to get links to the Pravda network stories edited into Wikipedia pages and public Facebook group postings, probably with the help of human contractors. Many AI companies give special weight to Facebook and especially Wikipedia as accurate sources. (Wikipedia said this month that its bandwidth costs have soared 50 percent in just over a year, mostly because of AI crawlers....) Last month, other researchers set out to see whether the gambit was working. Finnish company Check First scoured Wikipedia and turned up nearly 2,000 hyperlinks on pages in 44 languages that pointed to 162 Pravda websites. It also found that some false information promoted by Pravda showed up in chatbot answers.
"They do even better in such places as China," the article points out, "where traditional media is more tightly controlled and there are fewer sources for the bots." (The nonprofit American Sunlight Project calls the process "LLM grooming".)

The article quotes a top Kremlin propagandist as bragging in January that "we can actually change worldwide AI."

Meta has disabled Apple Intelligence features across its iOS applications, including Facebook, WhatsApp, and Threads, according to Brazilian tech blog Sorcererhat Tech. The block affects Writing Tools, which enable text creation and editing via Apple's AI, as well as Genmoji generation. Users cannot access these features via the standard text field interface in Meta apps. Instagram Stories have also lost previously available keyboard stickers and Memoji functionality.

While Meta hasn't explained the decision, it likely aims to drive users toward Meta AI, its own artificial intelligence service that offers similar text and image generation capabilities. The move follows failed negotiations between Apple and Meta regarding Llama integration into Apple Intelligence, which reportedly collapsed over privacy disagreements. The companies also maintain ongoing disputes regarding App Store policies.

Meta CEO Mark Zuckerberg considered resetting all Facebook users' friend connections to boost the platform's declining relevance, according to internal emails revealed Monday in a landmark FTC antitrust trial. In a 2022 message to executives, Zuckerberg proposed "wiping everyone's graphs and having them start again," referring to users' friend networks. Facebook head Tom Alison questioned the idea's viability, citing Instagram's reliance on friend connections. Zuckerberg later testified that the plan was never implemented and that Facebook has "evolved" from its original purpose.

The FTC argues Meta violated competition laws by acquiring Instagram ($1B) and WhatsApp ($19B) as part of a "buy or bury" strategy outlined in Zuckerberg's 2008 email stating, "It is better to buy than compete."

An anonymous reader shares a report: An attorney for the Federal Trade Commission told a judge that Facebook, fearing the competitive threat of Instagram posted to their social media network, acquired both as a way to "neutralize" the rival. "They decided that competition was too hard," the FTC's attorney, Daniel Matheson, said in his opening statement in the government's antitrust case against the Meta Platforms social media empire.

He argued that with Meta's monopoly in social media, "consumers do not have reasonable alternatives they can turn to," even as satisfaction has declined. At stake is the potential breakup of Facebook-parent Meta, as the government has zeroed in on the 2012 acquisition of Instagram and 2014 purchase of WhatsApp.

Stanford law school graduate Peter Thiel later co-founded Facebook, PayPal, and Palantir. But in 2010 Thiel also created the Thiel Fellowship, which annually gives 20 to 30 people under the age of 23 $100,000 "to encourage students to not stick around college." (College students must drop out in order to accept the fellowship.)

And now Palantir "is taking a similar approach as it maneuvers to attract new talent," reports financial news site The Street: The company has launched what it refers to as the "Meritocracy Fellowship," a four-month internship program for recent high school graduates who have not enrolled in college. The position pays roughly $5,400 per month, more than plenty of post-college internship programs. Palantir's job posting suggests that the company is especially interested in candidates with experience in programming and statistical analysis.
Palantir's job listing specifically says they launched their four-month fellowship "in response to the shortcomings of university admissions," promising it would be based "solely on merit and academic excellence" (requiring an SAT score over 1459 or an ACT score above 32.) "Opaque admissions standards at many American universities have displaced meritocracy and excellence..." As a result, qualified students are being denied an education based on subjective and shallow criteria. Absent meritocracy, campuses have become breeding grounds for extremism and chaos... Skip the debt. Skip the indoctrination. Get the Palantir Degree...

Upon successful completion of the Meritocracy Fellowship, fellows that have excelled during their time at Palantir will be given the opportunity to interview for full-time employment at Palantir.

A former Facebook employee/whistleblower alleges Meta's AI model Lllama was used to help DeepSeek.

The whistleblower — former Facebook director of global policy Sarah Wynn-Williams — testified before U.S. Senators on Wednesday. CBS News found this earlier response from Meta: In a statement last year on Llama, Meta spokesperson Andy Stone wrote, "The alleged role of a single and outdated version of an American open-source model is irrelevant when we know China is already investing over 1T to surpass the US technologically, and Chinese tech companies are releasing their own open AI models as fast, or faster, than US ones."

Wynn-Williams encouraged senators to continue investigating Meta's role in the development of artificial intelligence in China, as they continue their probe into the social media company founded by Zuckerberg. "The greatest trick Mark Zuckerberg ever pulled was wrapping the American flag around himself and calling himself a patriot and saying he didn't offer services in China, while he spent the last decade building an $18 billion business there," she said.
The testimony also left some of the lawmakers skeptical of Zuckerberg's commitment to free speech after the whistleblower also alleged Facebook worked "hand in glove" with the Chinese government to censor its platforms: In her almost seven years with the company, Wynn-Williams told the panel she witnessed the company provide "custom built censorship tools" for the Chinese Communist Party. She said a Chinese dissident living in the United States was removed from Facebook in 2017 after pressure from Chinese officials. Facebook said at the time it took action against the regime critic, Guo Wengui, for sharing someone else's personal information. Wynn-Williams described the use of a "virality counter" that flagged posts with over 10,000 views for review by a "chief editor," which Democratic Sen. Richard Blumenthal of Connecticut called "an Orwellian censor." These "virality counters" were used not only in Mainland China, but also in Hong Kong and Taiwan, according to Wynn-Williams's testimony.

Wynn-Williams also told senators Chinese officials could "potentially access" the data of American users.

Facebook Marketplace has emerged as the dominant feature within the social media platform, amassing 1.2 billion monthly active buyers by 2023 and overtaking eBay as a peer-to-peer selling platform. According to recent data, approximately 16 percent of Facebook's monthly active users now access the site exclusively to participate in Marketplace.

The feature's growth accelerated following the pandemic's supply chain disruptions and subsequent inflation, which increased demand for used goods. Facebook reports that Marketplace is attracting younger demographics who have otherwise abandoned the platform's social features.

This shift represents a fundamental transformation of Facebook's core function from "digital connector" to "digital bazaar," with the platform increasingly hosting transactions rather than social connections.

Meta says in its Llama 4 release announcement that it's specifically addressing "left-leaning" political bias in its AI model, distinguishing this effort from traditional bias concerns around race, gender, and nationality that researchers have long documented. "Our goal is to remove bias from our AI models and to make sure that Llama can understand and articulate both sides of a contentious issue," the company said.

"All leading LLMs have had issues with bias -- specifically, they historically have leaned left," Meta stated, framing AI bias primarily as a political problem. The company claims Llama 4 is "dramatically more balanced" in handling sensitive topics and touts its lack of "strong political lean" compared to competitors.

Meta is partnering with Blumhouse to launch "Movie Mate" technology that encourages moviegoers to use their phones during theatrical screenings, beginning with an April 30 showing of "Megan" at Blumhouse's "Halfway to Halloween Film Festival." According to Variety, the system enables viewers to chat with a Megan-themed AI chatbot, answer trivia questions, and access behind-the-scenes information while watching the film in theaters.

On Bluesky, the joke's on you if you don't get the joke. The social network has become a "refuge" for those fleeing X and Threads, but its growing pains include a serious case of humor-impairment. When Amy Brown jokingly posted she was "screaming, crying, and throwing up" about price differences between Ohio and California Walgreens, literal-minded users scolded her for exaggerating. Brown, a former Wendy's social media manager who got banned from X after impersonating Elon Musk, puts it simply: "We're both speaking English, but I'm speaking internet."

This clash stems from Bluesky's oddly mixed population: irony-steeped Twitter refugees mingling with earnest Facebook transplants and MSNBC viewers who took the plunge after seeing the platform mentioned on shows like Morning Joe. "It's riff collapse," says cartoonist Mattie Lubchansky, describing how her obviously absurd Oscar post triggered sincere movie recommendations.

"Gen Z is rediscovering Tumblr — a chaotic, cozy corner of the internet untouched by algorithmic gloss and influencer overload..." writes Fast Company, "embracing the platform as a refuge from an internet saturated with influencers and algorithm fatigue." Thanks to Gen Z, the site has found new life. As of 2025, Gen Z makes up 50% of Tumblr's active monthly users and accounts for 60% of new sign-ups, according to data shared with Business Insider's Amanda Hoover, who recently reported on the platform's resurgence. User numbers spiked in January during the near-ban of TikTok and jumped again last year when Brazil temporarily banned X. In response, Tumblr users launched dedicated communities to archive and share their favorite TikToks...

To keep up with the momentum, Tumblr introduced Reddit-style Communities in December, letting users connect over shared interests like photography and video games. In January, it debuted Tumblr TV — a TikTok-like feature that serves as both a GIF search engine and a short-form video platform. But perhaps Tumblr's greatest strength is that it isn't TikTok or Facebook. Currently the 10th most popular social platform in the U.S., according to analytics firm Similarweb, Tumblr is dwarfed by giants like Instagram and X. For its users, though, that's part of the appeal.
First launched in 2007, Tumblr peaked at over 100 million users in 2014, according to the article. Trends like Occupy Wall Street had been born on Tumblr, notes Business Insider, calling the blogging platform "Gen Z's safe space... as the rest of the social internet has become increasingly commodified, polarized, and dominated by lifestyle influencers." Tumblr was also "one of the most hyped startups in the world before fading into obsolescence — bought by Yahoo for $1.1 billion in 2013... then acquired by Verizon, and later offloaded for fractions of pennies on the dollar in a distressed sale.

"That same Tumblr, a relic of many millennials' formative years, has been having a moment among Gen Z..." "Gen Z has this romanticism of the early-2000s internet," says Amanda Brennan, an internet librarian who worked at Tumblr for seven years, leaving her role as head of content in 2021... Part of the reason young people are hanging out on old social platforms is that there's nowhere new to go. The tech industry is evolving at a slower pace than it was in the 2000s, and there's less room for disruption. Big Tech has a stranglehold on how we socialize. That leaves Gen Z to pick up the scraps left by the early online millennials and attempt to craft them into something relevant. They love Pinterest (founded in 2010) and Snapchat (2011), and they're trying out digital point-and-shoot cameras and flip phones for an early-2000s aesthetic — and learning the valuable lesson that sometimes we look better when blurrier.

More Gen Zers and millennials are signing up for Yahoo. Napster, surprising many people with its continued existence, just sold for $207 million. The trend is fueled by nostalgia for Y2K aesthetics and a longing for a time when people could make mistakes on the internet and move past them. The pandemic also brought more Gen Z users to Tumblr...

And Tumblr still works much like an older internet, where people have more control over what they see and rely less on algorithms. "You curate your own stuff; it takes a little bit of work to put everything in place, but when it's working, you see the content you want to see," Fjodor Everaerts, a 26-year-old in Belgium who has made some 250,000 posts since he joined Tumblr when he was 14... Under Automattic, Tumblr is finally in the home that serves it, [says Ari Levine, the head of brand partnerships at Tumblr]. "We've had ups and downs along the way, but we're in the most interesting position and place that we've been in 18 years," he says... And following media companies (including Business Insider) and social platforms like Reddit, Automattic in 2024 was making a deal with OpenAI and Midjourney to allow the systems to train on Tumblr posts.

"The social internet is fractured," the article argues. ("Millennials are running Reddit. Gen Xers and Baby Boomers have a home on Facebook. Bluesky, one of the new X alternatives, has a tangible elder-millennial/Gen X vibe. Gen Zers have created social apps like BeReal and the Myspace-inspired Noplace, but they've so far generated more hype than influence....")

But in a world where megaplatforms "flatten our online experiences and reward content that fits a mold," the article suggests, "smaller communities can enrich them."

It's "a milestone for Meta AI and for open source," Mark Zuckerberg said this weekend. "For the first time, the best small, mid-size, and potentially soon frontier [large-language] models will be open source."

Zuckerberg anounced four new Llama LLMs in a video posted on Instagram and Facebook — two dropping this weekend, with another two on the way. "Our goal is to build the world's leading AI, open source it, and make it universally accessible so that everyone in the world benefits."

Zuckerberg's announcement: I've said for a while that I think open source AI is going to become the leading models. And with Llama 4 this is starting to happen.

- The first model is Llama 4 Scout. It is extremely fast, natively multi-modal. It has an industry-leading "nearly infinite" 10M-token context length, and is designed to run on a single GPU. [Meta's blog post says it fits on an NVIDIA H100]. It is 17 billion parameters by 16 experts, and it is by far the highest performing small model in its class.

- The second model is Llama 4 Maverick — the workhorse. It beats GPT-4o and Gemini Flash 2 on all benchmarks. It is smaller and more efficient than DeepSeek v3, but it is still comparable on text, plus it is natively multi-modal. This one is 17B parameters x 128 experts, and it is designed to run on a single host for easy inference.

This thing is a beast.
Zuck promised more news next month on "Llama 4 Reasoning" — but the fourth model will be called Llama 4 Behemoth. "This thing is massive. More than 2 trillion parameters." (A blog post from Meta AI says it also has a 288 billion active parameter model, outperforms GPT-4.5, Claude Sonnet 3.7, and Gemini 2.0 Pro on STEM benchmarks, and will "serve as a teacher for our new models.")

"I'm not aware of anyone training a larger model out there," Zuckberg says in his video, calling Behemoth "already the highest performing base model in the world, and it is not even done training yet."

"If you want to try Llama 4, you can use Meta AI in WhatsApp, Messenger, or Instagram Direct," Zuckberg said in his video, "or you can go to our web site at meta.ai." The Scout and Maverick models can be downloaded from llama.com and Hugging Face.

"We continue to believe that openness drives innovation," Meta AI says in their blog post, "and is good for developers, good for Meta, and good for the world." Their blog post declares it's "The beginning of a new era of natively multimodal AI innovation," calling Scout and Maverick "the best choices for adding next-generation intelligence." This is just the beginning for the Llama 4 collection. We believe that the most intelligent systems need to be capable of taking generalized actions, conversing naturally with humans, and working through challenging problems they haven't seen before. Giving Llama superpowers in these areas will lead to better products for people on our platforms and more opportunities for developers to innovate on the next big consumer and business use cases. We're continuing to research and prototype both models and products, and we'll share more about our vision at LlamaCon on April 29...

We also can't wait to see the incredible new experiences the community builds with our new Llama 4 models.
"The impressive part about Llama 4 Maverick is that with just 17B active parameters, it has scored an ELO score of 1,417 on the LMArena leaderboard," notes the tech news site Beebom. "This puts the Maverick model in the second spot, just below Gemini 2.5 Pro, and above Grok 3, GPT-4o, GPT-4.5, and more.

"It also achieves comparable results when compared to the latest DeepSeek V3 model on reasoning and coding tasks, and surprisingly, with just half the active parameters."

Ultimately "move fast and break things" means breaking other people's things. Or, possibly worse, going full 'The Talented Mr Ripley': slowly feeling so entitled to the things you are enamored of that you end up clubbing out the brains of your beloved in a boat.

A former Facebook director of global policy recently published "the book Meta doesn't want you to read," a scathing takedown of top Meta executives titled Careless People: A Cautionary Tale of Power, Greed, and Lost Idealism.

But Wednesday RestofWorld.org published additional thoughts from Meta's former head of public policy for Bangladesh (who is now an executive director at the nonprofit policy lab Tech Global Institute). Though their time at Facebook didn't overlap, they first applaud how the book "puts a face to the horrific events and dangerous decisions."

But having said that, "What struck me is that what isn't included in Careless People is more telling than what is." By 2012 — one year after joining Facebook — Wynn-Williams had ample evidence of the platform's role in enabling violence and harm upon its users, and state-sanctioned digital repression, yet her memoir neither mentions these events nor the repeated warnings to her team from civil society groups in Asia before the situation escalated... In recounting events, the author glosses over her own indifference to repeated warnings from policymakers, civil society, and internal teams outside the U.S. that ultimately led to serious harm to communities.

She briefly mentions how Facebook's local staff was held at gunpoint to give access to data or remove content in various countries — something that had been happening since as early as 2012. Yet, she failed to grasp the gravity of these risks until the possibility of her facing jail time arises in South Korea — or even more starkly in March 2016, when Facebook's vice president for Latin America, Diego Dzodan, was arrested in Brazil. Her delayed reckoning underscores how Facebook's leadership remains largely detached from real-world consequences of their decisions until they become impossible to ignore.

Perhaps because everyone wants to be a hero of their own story, Wynn-Williams frames her opposition to leadership decisions as isolated; in reality, powerful resistance had long existed within what Wynn-Williams describes as Facebook's "lower-level employees."
Yet "Despite telling an incomplete story, Careless People is a book that took enormous courage to write," the article concludes, calling it an important story to tell.

"It goes to show that we need many stories — especially from those who still can't be heard — if we are to meaningfully piece together the complex puzzle of one of the world's most powerful technology companies."

In 1999 Slashdot reader Jeremie announced "a new project I recently started to create a complete open-source platform for Instant Messaging with transparent communication to other IM systems (ICQ, AIM, etc)." It was the first release of the eXtensible Messaging and Presence Protocol, and by 2008 Slashdot was asking if XMPP was "the next big thing." Facebook even supported it for third-party chat clients until 2015.

And here in 2025, the chair of the nonprofit XMPP Standards Foundation is long-time Slashdot reader ralphm, who is now issuing this call to action at XMPP.org: The European Digital Markets Act (DMA) is designed to break down walled gardens and enforce messaging interoperability. As a designated gatekeeper, Meta—controlling WhatsApp and Messenger—must comply. However, its current proposal falls short, risking further entrenchment of its dominance rather than fostering genuine competition. [..]

A Call to Action

The XMPP Standards Foundation urges Meta to adopt XMPP for messaging interoperability. It is ready to collaborate, continue to evolve the protocol to meet modern needs, and ensure true compliance with the DMA. Let's build an open, competitive messaging ecosystem—one that benefits both users and service providers.

It's time for real interoperability. Let's make it happen.

Meta is considering a paid subscription in the UK that would remove advertisements from its platform. The BBC reports: Under the plans, people using the social media sites could be asked to pay for an ad-free experience if they do not want their data to be tracked. Meta already provides ad-free subscriptions for Facebook and Instagram users in the EU, starting from euros (5 pounds) a month. A spokesperson for the firm said the company was "exploring the option" of offering a similar service in the UK.

They said the firm was "engaging constructively" with the UK data watchdog about the subscription service, following a consultation in 2024. The Information Commissioner's Office previously said it expected Meta to consider data protection concerns before it launched an ad-free subscription. Meta says personalized advertising allows its platforms to be free at the point of access.

Guidance issued by the regulator in January states that users must be presented with a genuine free choice. Social media platforms such as Meta heavily rely on ad revenues, and the company says personalised advertising allows its platforms to be free. Advertising accounted for more than 96% of its revenue in its latest quarterly financial results.
