There's lots of other things to worry about in the iCloud ecosystem anyway. The iCloud backups that devices make aren't encrypted or protected at all by Apple's two factor authentication. Apple can pick and export these at will. Alternately, plug in somebodies email and phished password, and you've got the entire history of their iMessage conversations in plain text, along with a complete copy of all their devices. I'm much more worried about that happening than an evil-Apple scenario. I doubt many people have strong AppleID passwords, or particularly unique ones either. Heck, I know people that share accounts to avoid paying for apps.
