Unfortunately for Google (and fortunately for the rest of us), they have no risk-free mechanism[1] to achieve this feat exclusively. Strategically, any sort of balkanization will mean Google's competitors can gather resources and improve technically while being shielded from competing with Google; Google would much rather bludgeon any nascent competitor early (by offering a better[2] product, today) before they grow any legs. ISPs, on the other hand, can approve service providers this via prioritization, or DNS-/traffic-level blocking. Google was cognizant early, which is why it became a fervent "net neutrality" supporter. 1.

"better" being measured by market success.
