It sounds like you weren't really asking a question, so much as indirectly asserting your opinion, and expecting everyone to agree with you. Or rather, putting the burden on others to prove that it didn't happen the way you think it happened. Which in my opinion happens to be a fairly naive interpretation.

It's beyond debate that big tech is dominated by liberals who hate Trump. This discussion is searching for an explanation for why up until recently these people regarded Trump as Hitler, where even allowing him to speak on their platforms was violence and terrorism, and now they're like welcome back, let's make "informed choices"! Do you really think the leftists in Facebook suddenly got wise and are now thoughtful, balanced centrists? Sorry that you don't like the way I presented the argument but what you're proposing lacks credibility.
