Well that depends. It depends on if Fascistbook and Twitter are platforms or publishers. If they are publishers they do not have to produce anything other than what they want. They can have writers submit to them all they want but they don't have to do anything about it.
If they are a platform then they are obligated to let their patrons say whatever they want. Where the obligation begins is with the person reading the comment. Just like in the public, you can say whatever you want but no one is obligated to listen to you. On a platform no one is obligated to read what you post.
Neither Fascistbook or Twitter are publishers. They are platforms. That is why Ted Cruz has been going after them so strongly.
What Fascistbook, Twitter and Google are doing is what the Democrats are going to put into law once Biden is sworn in as president. They are going to work overtime in silencing their opposition. That is what Socialists do. Biden isn't a Socialist but the rest of the Dems are and like all Socialists they crave power and control. They will turn this nation into a nation that resembles Nazi Germany.
