Ah, but does it? China is currently going through a period of peace and incredible growth (per capita income has grown about 130x since 1960, in constant dollars). The people are safe, secure, and enjoying opportunities their grandparents couldn't even imagine.
And I suspect that if you polled in China, you'd find a majority agree with the regulations on speech, and sincerely so (not saying yes out of fear). Meanwhile, things are much freer than they were. I'm currently reading a Chinese novel, The Three Body Problem, set partly in the Cultural Revolution, and it pulls no punches about how awful it was.
Even here, on an American-centric discussion full of grossly privileged white American men, you'll find most agree on some regulation of speech. It's just a question of degree.
