That's not how this works. That's not how any of this works. They absolutely have every right to and often are right to. That doesn't mean they're not hypocritical at times. But just because someone is hypocritical doesn't mean they're wrong.

China exerts extreme control over businesses that operate from there. That's a simple fact. This individuals motivations aren't extremely relevant.

How does any of that change the fact that the Chinese government has tight controls over all businesses within their border? Again that is a simple fact. And makes this concern not unwarranted. Let's phrase it this way. Would you be defending a US state-controlled organization from doing similar in China? I doubt it.
