Earlier quoted context omitted.
I don't think Noam Chomsky has ever been sympathetic to the USSR, he just said that the US was not much better than USSR. For example in that speach he clearly states that USSR was a a flawed totalitarian system from the start https://www.youtube.com/watch?v=06-XcAiswY4 (he has in fact also stated many times that his political views were indeed censored in the US)
When Western intellectuals like Chomsky say they have been "censored", they mean that that their publishing house asked them to leave out or add stuff because they felt that such changes would help the book sell better, as their goal was to make money off authors they published. That's quite a bit different from the threats of jail time that Eastern Bloc intellectuals faced.
"Wasn't much better than USSR" is such bullshit on so many levels that it's hard to even to begin. In the US:
- you didn't have quotas to write "correct literature"
- you wouldn't disappear in a gulag for 10 years
- you didn't have to worry about standing in a queue for 1-2h to get fresh bread and sausage (it's easier to contemplate stupid shit when you don't have to worry about food)
- you didn't get assigned to a specific workplace where you HAD to work
- the books you read didn't have ideological crap (due to quotas) like "and children stopped starving because country X is a part of a friendly USSR"
I skipped not relevant bits but probably I still missed quite a few because I can only relay what my parents and others told me (I was born in the late 80s so I didn't get to experience the full glory of USSR).
EDIT: I forgot to mention a well-known practice of labelling people physically ill[1], getting them into physical wards, and pumping them with drugs until they are no longer "a thread". There is no need for a trial, and you can be held there indefinitely.
