I think you're conflating not shaping traffic at the ISP or Backbone level with something else. The something else in this case is making requests to URLs a consumer of a page may or may not be vetting. If anything it's not treating all contents of a page as equal, and I think that's okay. We already do this with prefetching hints, ordering elements on a page (e.g. styling before scripting), and sometimes consumer driven more invasive approaches (ad blocking, monkey patching sites -- e.g. Reddit Enhancement Suite, etc.). Sure this is pretty heavy handed, but it's quite likely that the other vendors will follow suit (though perhaps with different priority, I doubt Google would do this to their own services).
