True, I've never heard of an official state established Q&A site. So there's even less danger of state suppression of rights in the case of the technology site.
I mean, first, I'm surprised at the implicit claim that most of the world's programmers do use Stack Exchange and abide by its policies. I don't have a Stack Exchange account. I occasionally run across it in Google searches, but I don't have to abide by any policies to read a website. And my company (which is in a regulated industry and is IP-sensitive) prohibits us from posting detailed information about our work externally without review by the security team, so I assume most (I certainly don't assume all) of my coworkers don't post to Stack Exchange from work / about their work. I can't remember the last time I heard a coworker (here or at a previous employer) say "I asked StackOverflow and they said....". There are a lot of companies and non-company employers (governments...) which will be equally sensitive about posting code.
Second, even if it were true that most of the world's programmers do use Stack Exchange, why do they have to? It's a company that's barely 10 years old. It's a site that's notorious for closing question as off topic. Surely there are other resources. Surely other sites could pop up. I specifically mentioned "established" churches because it is no such thing - it's popular because people want to use it, not because anyone is obligated to. If people want to use something else, or nothing at all, they can. If someone figures out how to disrupt Stack Exchange, nobody is stopping them. "Crime" is a term that applies to violations of rules set by the government, which you are obligated to follow - it does not apply to violations of rules set by private parties.
Finally, the policies in question were applied in this instance to a moderator, not a user. I don't believe that most of the world's programmers have to be a moderator. (And, again, given that StackOverflow is notorious for editing questions to make them more generally useful even at the risk of making the question useless for the individual asker, I assume they would at most rephrase the question to be policy-compliant instead of banning the user.)
