The problem here is that when I buy an iPhone, even though I paid for it, it is not really mine because I can only install Apps that Apple approves of.
Kind of like buying a car and only being able to drive it to certain locations approved by the car manufacturer. Of course, the car manufacturer would be protecting the safety of kids so that is alright? No! No one would accept that. And there is no reason to accept Apple's shared ownership claim of the phone I purchased.
