Since I can't edit my last reply, and I misread this originally: No, I don't have any evidence that they do. Nor am I saying that they violate their privacy policy. I'm simply saying that we don't know what they do with their user's data.
Their specific question was if you had evidence of apple violating their own privacy policy. I'd agree that what they're doing is unethical, but it's not done secretly, and I'd expect that in China their privacy policy makes this clear.
Do you have evidence of Apple violating their privacy policy?
Actually, you are correct, I apologize. I mis-read the question and no, I don't have any evidence of Apple violating their privacy policy. But that's not what I'm stating. I'm only stating that we don't know what they do with our data.
Apple’s a publicly-held company, and China is among the largest markets for consumer electronics. Apple’s shareholders wouldn’t be too pleased if Apple simply said “nah” to such a market, and Apple’s obligations are ultimately to its shareholders.
The situation might be different if Apple was a different kind of company, but it is what it is.
