Trump looks like he's trying to draw a line that you want to just be a platform and have all those immunities to the content, you can't step in and editorialize. He's putting himself in a win/win situation that either has Twitter backing down, Trump being banned and letting him play the victim, Twitter embracing censorship that will turn people away once all the twitter losers finish with their multicolored clap emojis for the day, or this going to court and it's established what the rules are for real which no one in Silicone Valley really wants, no matter what they say to virtue signal.
It's why Zuckerberg looks like he's trying as hard as he can to distance himself/Facebook from what Twitter is doing and say they can't police people.
