That's a take I hadn't considered. Google's danger as a monopoly comes more from the situation in which you have to pay them to sell anything on the web. That's a much more interesting argument.
And one that the GOP will actually care about. Truth be told the GOP doesn't care about the average American locked into 1/2 ISPs available to them, but when businesses are the ones being price gouged you can bet the GOP will be the one to save the day by regulating big tech.
