Apple has a lot to gain from controlling user experience, preventing malware, and protecting their 30% cut of software costs. Its not merely that they don't have much to gain from protecting users from snooping girlfriends. In almost every other instance they actually stand to gain from helping the other side.

Apple has every reason to help your mom/dad/boss/school ensure that you don't misuse THEIR property.

Your perspective seems to be mostly unfounded speculation that doesn't hold water.
