I highly doubt that any 230 repeal will manage to make it through, for one reason: money. Billion dollar lobbying entities backed by google, facebook, et al will fight this tooth and nail, because even if this 230 repeal would benefit them int he short run by eliminating their competitors, they know that no modern internet company would survive. To avoid hundreds of lolsuits per day, youtube, facebook, twitter, ece would have to vet every single post, and that would be far too expensive to do, since you couldnt risk an AI fucking up and letting a post through. The highly mediated system would also obliterate engagement from users, dramatically reducing data collection, ad interaction, and overall income, along with halting the political power of these institutions. Even if the loss of money wouldnt didnt stop them,t he lost of political power would.
