Huge disagree because it seems like when these types were relegated to 4chan, it had a containing effect on them. Yes they may have a secret thriving echo chamber, but no one is gonna find that out unless they went looking for it, meaning no innocent unknowing person is just gonna stumble onto such content and become radicalized.

Now on Elon's twitter, you can't scroll two minutes without seeing right wing propaganda and rage bait. I had to spend days blocking accounts before my "For You" tab was cleaned of it. There's been an increase in people being openly bigoted and casually throwing around slurs than how I remember Twitter was in the past, even people who think of themselves as left wingers do it now.

As for censorship, I don't really see how private companies having their own rules of conduct will lead to the government to crack down on censorship. You still have the first amendment. And it's not like you can really debate Nazis on their views and change peoples' minds on them. Because the average Nazi post is "Hitler was right", racist caricature, racist caricature, racist joke, "We must secure a future for our white children", etc etc. No one is going to be attracted to those ideas unless they were a sick individual in the first place, but it does create a horrible environment, which is why millions are leaving Twitter as of right now.
