I'm not really sure it's Apples job to advocate for policies in a foreign country. They're a business, not a nation state. I think the extent to which privacy is valued is up for the Chinese to decide. Not really a fan of American companies engaging in corporate activism abroad.
Define "foreign" country in the context of a multinational corporation? I'm not sure I understand what the significance of that word is. Companies can and do attempt to sway political policies in their favor in whatever country they are operating in, regardless of where that company was founded.
Almost all people are employed by companies. If companies don’t advocate for human rights that means that almost noone will except for politicians and the unemployed.
We should expect more civil responsibility from companies since they have a strong influence over the time, speech, health, purchasing-power, and labor of nearly all citizens.
