Android devices don't even have to include the Google app marketplace. A manufacturer or network can put their own marketplace on the device instead, which makes it pretty much like every pre-iOS smartphone platform (at least in that regard). I don't think that any single manufacturer has the leverage to tell the networks to stay out of the device OS and just be dumb bit transporters. I suppose Nokia could do it, but the idea's pretty unthinkable for those guys.
