There's definitely a shortage of general computing devices that I can carry in my pocket.
Your (very strange) analogy reminds me of when I was in 3rd grade, and we were having lunch. There was a substitute teacher that day. I had peanut butter and jelly (packed by my mom), and started putting some potato chips inside it. The teacher came over, asked what I was doing, and said "stop; we don't do that here".
It was a dumb thing for her to say then, and it's dumb to tell us what we can and can't do with our devices now.
Ferrari has a list of rules you must follow in order to purchase their cars. If you violate the rules they will try to take back your car and anyway you will be banned for life from purchasing another of their cars.
For example they only allow a certain selection of colours for their cars.
So no, you are not allowed to do whatever you want with your device. That was never something completely true.
If I was working at Apple I would propose this feature: if you see the user changing the OS or modifying it in ways that are not acceptable to Apple then the user will be blacklisted from support and ideally from buying another Apple product. I would probably make some big bucks from bonuses.
Like that time at the Ferrari dealership when some dumb lady wanted a Ferrari in pink and the dealer told her "No" and pointed to the door: "Don't let the door hit you on your way out".
See? The companies are also allowed to tell you "No!". Freedom and all...
