I'm not sure if I'm responding to exactly what you said, but I would say that Apple has been anything but silent about user privacy. Tim Cook has said on multiple occasions that he values user privacy very highly, that Apple does not want to collect user data (and thus anonymises/randomises things which do have to flow through them, or uses end-to-end encryption for things that they don't need to process and return) and has-not/will-not install government backdoors.
Regardless of what they say, they have a bad track record and motivation to maximise profit so public assurances are about as valuable as BP's assurance on not letting oil escape from their kit in future.
I'd like to hear more about their bad track record. Also, Apple profits from selling hardware, not user data. They're just not structured to profit from user data. They could change that, of course. It'd be similar to Google becoming a hardware company :)
