Haven't they just indefinitely "disappeared" even famous technology leaders, famous billionaires, famous celebrities, famous athletes, etc. if they say something the government doesn't approve of? As a BBC headline put it "Why do Chinese billionaires keep vanishing?" After one famous athlete said something the government did not approve of, that same day her name got blocked from even being searched for, her posts and accounts were taken down, and she was disappeared. Heck, even names of people or modern incidents that China doesn't want mentioned get proactively blocked from end users discussing them. And there's a lot more too. Are companies really willing to be honest in that kind of environment?
I guess your point is that at least those outside China will at least hear when they “disappear” someone especially famous, but my argument is that almost no one is going to be willing to speak out, especially for a cause like whether their AI hacked someone?
