Apple’s ad network gets ‘preferential access to users’ data’ vs Facebook, Google

Apple exempts all their iOS software from their own privacy scaremongering. iOS never pops up a scary dialog warning you that Camera has accessed your location twice in the last week, even though Camera accesses your location every time you start it. There is a completely separate iOS privacy regime for Apple's own apps.

The idea is that we trust Apple already by using their computers. If Apple was sending that data back to their servers each time then that would ruin their reputation, but there are no such guarantees for third-party applications. Yes, theoretically, Apple reviews third party code, but it is easy enough to slip something small by them.
