Remember that Facebook and Twitter only acted after the fact. For them, Trump was too big to censor too. They only took action days before he is out of office when it was guaranteed he would leave.
That's not altogether true. They've been footnoting his posts where there's been a mismatch with reality.
FB and Twitter didn't deplatform Trump because he was a nasty bastard who was inciting revolt. They did it because the Democrats won and they want to suck up.
Yes that's exactly what I'm saying.
They didn't deplatform him until he crossed a line in terms of violence; they didn't deplatform him right after the presidential or even the Georgia races were called.
