Sort of a side note here, but I think this is a big misunderstanding about Apple. Sounds crazy, I know, but hear me out before judging.
I think with Apple it's more about allowing the end user (the real end user, not the end user's boyfriend/girlfriend/wife/husband, child/sibling/parent, boss/teacher/roommate etc.) to have control over their own information.
In order to enforce this end user control, Apple needs to lock out rogue programs. It can't do so 100%, but it tries to get as close as reasonably possible. They try even harder with mobile devices, because mobile devices tend to be so personal and capture so much private information of one individual.
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.
Also because users are used to their phones being able to do less than a laptop. "The appstore doesn't have it" is a legitimate reason to not be able to use a program on a phone but not a Windows machine (for example)
