It’s hard to take down sites on Tor. Usually impossible without the full weight of the FBI/CIA. I agree with the user above: we can do decentralised communication without censorship. Of course if you start from the faulty premise that online discourse needs to occur on one of a handful of censored platforms then that’s impossible.
And so tor has a reputation of mainly being used for illegal things - because it is - and several countries just block the entire thing.
