I don't think they sell it like Google or Samsung. For example Apple does not have a location intelligence team dedicated to driving revenue for store brands or targeting users that go there using precise geo location data.
So in other words, "companies operating within a nation are expected to abide by the laws of that nation"?
Apple structures their systems to limit the data they can turn over by request, and documents what data they do turn over. What else do you believe they should be doing?
Google isn't. They are the advertising engine and sell to advertisers for reach, just like Facebook does.
I trust Apple about as far as I can throw them too. They are inherently anti-consumer rights everywhere in their ecosystem. The "Privacy" angle is just PR.
I would say it is PR as much as it is a strategic differentiation. Their business model is too sell products and services directly to consumers. This is different from Microsoft who is selling to businesses who need data protection, but actually want to be able to monitor their employees and Google who wants to leverage your data / behavior to allow advertisers to effectively target you with ads.
None of the big companies expressly sell your information. Not because they are altruistic, but because it is an asset that they want to protect so they can rent to the next person.
At 3 trillion Dollars of market cap they are a capitalistic hellscape and do everything in their power to benefit their own interests, which are not yours.
Google and Samsung do.
