Realistically, though, Google have always seemed to view HTML5 as being a very good thing, since the Web is their bread and butter. Android seems to be more of a hedge against other vendors' platform dominance than an attempt by Google to lock everything down -- thus why Google actually exerts little control over Android distribution.

And I can see a good argument for blocking the open Web being in Apple's interests, but again, historically they've been going as fast as anyone else. They might not move as fast as I'd like, but they're not lagging.
