The issue with free speech platforms is they attract a crowd of people whose only narrative is one that can't be said in other places. It isn't a narrative of truth, it is one of hate and bigotry.
I've seen few examples where objective truth is banned. I have, however, seen a lot of Nazis get banned.
I’ve seen this again and again, people will see an ocean of normal content anywhere free speech is allowed and laser-focus on the single floating turd.
They’ll then mischaracterize the entire ocean as the turd, it’s like they have no sense of proportionality.
I'm happy to be shown to be wrong, but from my experience what you are saying doesn't exist.
