That seems crazy.
So let's say, hypothetically, that Apple comes out with iOS 8 this year and iOS 8 lacks an app store, safari web browser, and text messing app. You're telling me it would be ok for Apple to do this because they can?
That would be a stupid thing for Apple to do, and they would lose lots of customers. Doing stupid things is not illegal. Not that Apple would do that, because they don't tend to do stupid things. But if they produce something that you don't like, then don't buy it and don't install it.
