What the Jan. 6 probe found out about social media, but didn’t report
The Jan. 6 committee's 845-page report offered few details of social media's role in the Capitol riot. Transcripts and an unreleased memo shows the committee knew more.
The Washington PostThis has been obvious for a very long time, and it's made the right-wing whining about "anti-conservative bias" that much more ridiculous.
And if you actually look at what "the Twitter files" show (what the actual screenshots shared by Musk's right-wing lackeys and not their biased commentary), it's mostly Twitter hemming and hawing over whether to actually enforce rules that were being broken on the regular by Republicans. That's not "anti-conservatives bias," that's preferential treatment for Republicans.
Twitter wasn't being run by out-of-control lefties. It was being run by capitalists who worried that if they enforced the rules of the platform consistently, that Republicans would throw a fit and keep dragging Jack Dorsey in front of congress to demand answers for why specific accounts get suspended.
So Twitter, which already had a pro-GOP bias in how it was managed, was then bought by a guy who sees it as his mission to eradicate "the woke mind virus" (by which he means anything vaguely liberal/different), and that's how we ended up with the complete and total cesspool its become.
