My problem is, like the App Store monopoly, this is like DRM. You don't really own your phone. There's a lot of stuff you could do with it, but Apple restricts you from doing anything with it they don't want you to do.

There's protecting people from shooting themselves in the foot, and then there's just being authoritarian. (Suddenly I'm starting to understand TigerJimmy's anti-socialism stance a little more.)

Gruber's argument basically hinges on "cross-platform apps suck". This may or may not be true, but it implies that apps developed using the official toolkit cannot suck.
