> they have strong initiative not to keep user data
What makes you say that? Lots of hacks and leaks shows that Apple only see Privacy as a word to sell stuff. It isn't something they code for if not forced by leaks and hacks (laws in the US also is against privacy by design).
Initiative doesn’t mean they follow it, especially for legacy projects.
While I do think that Apple is using privacy mostly for PR, I wouldn’t be too cynical. It’s likely that new projects are built with higher privacy standards. But also, I wouldn’t be too surprised if their PR department is writing checks that their engineering teams cannot fully cash.
