It’s still not the same as selling your data to third parties, with all the many very considerable additional privacy and accountability problems that entails. It’s also not using your data to provision ads on third party sites and apps. I’ve seen people claim Apple does both of those things here before, and the fact is they don’t.
What they are just starting to do is no different from Amazon using your past purchases to place ads on their own site. I have no problem with that either.
If your going to criticise them and think what they are doing is wrong, fine. That’s fair, but could people at least get what they're complaining about factually correct.
