I hate it, but it's the best we have until/unless government improves our terribly weak consumer protection & privacy laws. I really hope the option's not taken away, nor Apple's position as a regulator significantly weakened, until/unless government steps in and solves the problems Apple's currently solving. At that point, sure, break them up, ban app store platform monopolies, whatever, fine, go for it. But please not yet.
I bet Libertarians would love to hear that, but even they probably wouldn't put their money into a company that has time-and-time-again been proven to be in the Governments pocket via PRISM, iCloud data requests and Greykey Bruteforcing. Sounds like a libertarian nightmare to me: you give your data to a private company, but they immediately betray you and share that information with the government.
...that of course doesn't mean that Apple shouldn't be regulated into the ground. It does imply that they won't be regulated though, as long as egregious data collection continues to appease our private and national interests.
What you _can_ buy from apple though is i) services where your data are not monetised to the highest bidder and ii) being part of a non-ad-supported culture which seems like a prerequisite for a functioning public discourse and political economy.
Similarly, a resident of a communist country could theoretically leave and buy things elsewhere, but in practice almost no one will because of the high overhead of moving countries.
