Google could take the high road by promoting the phones that offer a fuller google experience than not on its own, maybe with some really good YouTube comparisons. Profile all of the good points about all of the Android phones, as best they can by region.
Sort of like direct-to-consumer marketing in pharma. "Ask your doctor about the HTC Incredible."
