Apple has been upfront from the get-go that their platform isn't open (they say that people who want to do things openly on iOS are free to make web apps; which I guess is nice, but sort of a brush-off).
I don't like the position Apple has taken. I agree that it's their prerogative to do so, and they argue that their position leads to a better product.
I've used several Android phones, and now an iPhone 4, and I think that they're right...and I hate that. I don't want them to be right, I want them to be proven wrong.
I think Android has absolutely worked to position themselves as a friend to "open" (with bullshit nebulously defined definitions of what "open" means). The entire content of that keynote is a gushing plea to friends of the open source movement (that you have an alternative to iOS).
And I think that Google's position of "open" since the launch of Android has been shitty (so yeah, I guess nothing has changed with the latest changes to Android), except that this yet another bullet point on the side against open.
Development on Android has always occurred in the dark, without feedback or input from the community at large. When a release is "ready", it's open-sourced, and then people are free to take the parts of Android which are included in that open release and do what they want with them. This is of course, long after Google's partners have had access to the source, so that they can prepare their phones for release.
I'd like for "open" to mean an open playground, where everyone is equal (and technology can compete on merits). Not where "everyone is equal, but some are more equal than others". But like Apple, Google is free to do this (I don't think they're in violation of any licenses with the way they release their code).
But I think it sucks, and I think it's crazy that I have to long for an actual "open" alternative to the supposedly "open" alternative to iOS.
