Probably in the EU, but that stuff gets squirreled in through private institutions here. Information clearing-houses like Facebook, Twitter, Reddit, etc. will take it upon themselves after encouragement from the media and the government.
Not sure why, but I feel like there’s some difference between being blocked by these media outlets and being sent to prison for 15 years and/or experiencing a kafkaesque process where your whole life is in shambles.
The constitution of the Russian Federation guarantees freedom of speech and prohibits censorship. I seem to recall the Soviet Union had a pretty spiffy constitution, too. The United States certainly did, during the Palmer Raids, during McCarthyism.
Constitutions alone do nothing. If we're not on guard, collectively, we could easily end up without freedom of speech and press in practice.
