I'll also point out that if Section 230 protections are removed, Donald Trump loses more than anyone. Nobody is going to carry his messages if they can be sued for their content. He'll have to make his own Twitter. His press conferences won't be broadcast live because the liability is too high. It is hilarious to me that Donald Trump is probably the largest beneficiary of Section 230 and he's the one that wants to remove it.
Section 230 is what lets the little guy exercise his or her right to free expression. It gives them a platform where they have an opportunity to let their opinion rise to the top. It saves them from having to buy their own printing press and build their own audience. Nobody is going to buy you a printing press if they're liable for everything you say. So what happens is you don't get to talk anymore.
