My opinion, is Apple lays out everything clearly in their TOS. You may have to dig to find out what the policies are but these policies are there.Why not? The die hard Apple fanboys have taken more on faith with similar reports about Samsung, Google/Android, and anything else that isn't Apple.
While I like Apple's offerings (mostly), even the MacBook Pro I'm typing on with it's incessant need for clean keys, I do not and have never subscribed to the myth that Apple is way above-board when it comes to privacy as compared to others. I think they do as the others do.
The "whistleblowing" of this contractor, which isn't whistleblowing" at all, probably will have some serious ramifications for that department and it should.
