A trove of internal documents turned over to the SEC provides new details of Facebook’s role in fomenting the storming of the U.S. Capitol, the Washington Post reports.

“Facebook has never publicly disclosed what it knows about how its platforms, including Instagram and WhatsApp, helped fuel that day’s mayhem. It rejected its own Oversight Board’s recommendation that it study how its policies contributed to the violence and has yet to fully comply with requests for data from the congressional commission investigating the events.”

“But thousands of pages of internal company documents disclosed to the Securities and Exchange Commission by the whistleblower Frances Haugen offer important new evidence of Facebook’s role in the events.”

New York Times: “Company documents show that the social network’s employees repeatedly raised red flags about the spread of misinformation and conspiracies before and after the contested November vote.”

“A new whistleblower affidavit submitted by a former Facebook employee Friday alleges that the company prizes growth and profits over combating hate speech, misinformation and other threats to the public,” the Washington Post reports.

“Twitter is publicly sharing research findings today that show that the platform’s algorithms amplify tweets from right-wing politicians and content from right-leaning news outlets more than people and content from the political left,” Protocol reports.

“The research did not identify whether or not the algorithms that run Twitter’s Home feed are actually biased toward conservative political content, because the conclusions only show bias in amplification, not what caused it.”

Former President Donald Trump’s “proprietary” new social network ’Truth Social’ is actually a thinly disguised fork of popular social network codebase Mastodon, Motherboard reports.

“Mastodon is a piece of open-source software that people can use to create their own social networks. The platform has a timeline style similar to Twitter.”

For members: Trump’s Social Media Grift

Kara Swisher and Walt Mossberg discuss Facebook on the Sway podcast and conclude the company is “fundamentally unethical” at its core.

Wall Street Journal: Facebook is rebuked by its own oversight board.

“Five members of the U.S. House Judiciary committee wrote to Amazon.com Inc’s chief executive Sunday, and accused the company’s top executives, including founder Jeff Bezos, of either misleading Congress or possibly lying to it about Amazon’s business practices,” Reuters reports.

Ars Technica: “For two years, he ran websites and Facebook groups that spread bogus stories, conspiracy theories, and propaganda. Under him was a dedicated team of writers and editors paid to produce deceptive content—from outright hoaxes to political propaganda—with the supreme goal of tipping the 2016 election to Donald Trump.”

“Through extensive efforts, he built a secret network of self-reinforcing sites from the ground up. He devised a strategy that got prominent personalities—including Trump—to retweet misleading claims to their followers. And he fooled unwary American citizens, including the hacker’s own father, into regarding fake news sources more highly than the mainstream media.”

“Pundits and governments just might have given Russia too much credit, he says, when a whole system of manipulating people’s perception and psychology was engineered and operated from within the US.”

“I have been hacked and my Twitter account has been erased. I know who has done this. I will take care of this. M Waters.”

Nieman Labs notes that when Facebook went down for nearly six hours earlier this week, traffic surged at news sites.

“We can’t count on Mark Zuckerberg to tell us the truth. He has lost all trust, if he ever had any.”

— Sen. Richard Blumenthal (D-CT), in a CNN interview on the Facebook CEO.

Washington Post: “After four years of almost continuous scandal, Facebook is approaching its latest controversy over political polarization and the toxic effects of social media in a more aggressive and defiant way than it has previously, say current and former employees, including executives who helped shape the company’s earlier responses.”

“Gone is the familiar script in which chief executive Mark Zuckerberg issues a formal apology — sometimes in long blogs on his personal Facebook page or over live-streamed video for a Congressional hearing — then takes responsibility and promises change.”

“In its place, the company has deployed a slate of executives to mount a public defense while quibbling with the details of allegations from Frances Haugen, the former project manager who left Facebook with tens of thousands of documents.”

Axios: Facebook’s perfect storm.

Facebook, Instagram and WhatsApp “abruptly went offline Monday morning, disrupting user access and communication in many countries for an extended period,” the Wall Street Journal reports.

“While even the biggest tech companies occasionally go offline unexpectedly, the duration and widespread nature of the disruption for Facebook and all its platforms is unusual.”

“A former Facebook employee says tens of thousands of pages of internal company research she has provided to the Securities and Exchange Commission prove Facebook is lying to the public and investors about the effectiveness of its campaigns to eradicate hate, violence and misinformation from its platforms,” CBS News reports.

“That former employee, who anonymously filed the complaints with federal authorities against Facebook last month, will reveal her identity and speak her mind in an interview airing Sunday night on 60 Minutes.”

The New York Times reports she’ll accuse Facebook of contributing to the Jan. 6 Capitol insurrection by “relaxing its security safeguards for the 2020 election too soon after Election Day.”
