Apple's restrictions do nothing but prevent things from "just working". It locks down where you can obtain apps, what you can do with them, and can even lock you out of something if there's a problem on Apple's end (example: iOS 4 was widely considered to be unusable on the iPhone 3G, yet it was impossible to downgrade unless you had the foresight to use circumvention tools in advance of iOS 4's release).

One could argue that DRM is required for there to be a thriving market in media, and therefore is to the user's benefit. Now, you don't believe that, I don't believe that, and maybe even the MPAA doesn't believe that, but the argument isn't invalid on its face. It's clear that restrictions which only limit users can be considered to be good for them. Apple's restrictions only limit users, yet you and many others argue that they're good for users.

I don't really care about Apple's intentions, care, or pride. I see Apple as pushing the entire world to a much worse model of computing. The MPAA, on the other hand, is fading into obsolescence one way or another.
