>Why don't these same people complain about third party browsers being completely banned on the iPad which has a huge share in the tablet market?

There are many third party browsers available on the App Store for iPad. I'm not sure where you got the idea that they're "banned"?

Those are Safari skins, not browsers.

Third-party browsers cannot do core things like implement their own JavaScript engine (which is why you're not going to see Firefox or Chrome for iOS unless Apple changes the rules).
