In other words, that filter that keeps Nazis, child predators, doxing, etc. off your favorite platform only exists because of section 230.
Now, one could argue that the biggest platforms (Meta, Youtube, etc.) can, at this point, afford the cost of full editorial responsibility, but repealing section 230 under this logic only serves to put up a barrier to entry to any smaller competitor that might dislodge these platforms from their high, and lucrative, perch. I used to believe that the better fix would be to amend section 230 to shield filtering/removal, but not selective promotion, but TikTok has shown (rather cleverly) that selective filtering/removal can be just as effective as selective promotion of content.
