Some interesting analysis in this article, but this is the same Google that brought Chrome to market despite providing majority funding for Firefox, and that went with a highly unusual auction model for its initial public offering, among other think-different actions. If Google’s leaders think they can accelerate the use of Internet services by attempting to radically change the wireless business in the United States, burning relationships with a few Android partners (such as Motorola) probably won’t be a constraint.
Another boat Google would be rocking is their Open Handset Alliance of various manufacturers who want to produce Android handsets. Google's goal is to get their software in front of as many eyeballs as possible. They're not Apple, who is looking for profitable hardware and not caring too much about market share; Google's advertising-based business model is all about market share. Portraying themselves as the only owners of the One True Android would actually lead to fewer Android phones, as appalled partners back out.
