They do, if you take a moralistic attitude, as op has. It’s hypocrisy. If you just don’t care about Chinese market then say so—don’t pretend you do so out of a moral obligation.

You're making assumptions about the beliefs of OP that aren't in evidence. A "moralistic attitude" (as you put it) can give greater weight to concerns about government censorship than to concerns about corporate respect for privacy rights. The two are quite different, even to an avowed anti-statist such as myself.

That’s why I stated it as a question.

I still think it’s hypocrisy to care about one and not the other. Those corporations are actually actively working to erode Internet freedoms, which affects everyone, not just a single country, and one that is not even democratic in the first place.

To get on your high horse over censorship in Asia while at the same time merrily include spying in your own code, as a simple convenience, nonetheless, is very much indefensible.
