Not elected people, not respecting the most basic of constitutional principles. Not only that, but you can't enforce your "set of principles" on billion of tweets each hour of the day, not by people at least, so you defer to bots, which are incapable of discerning what is free speech. They can't apply your principles with the discernment of a human, they can't enforce what's legal or illegal, like they can't recognize copyrighted music from public domains ones.
