Google should instead throw a couple more billions at the SpaceX mesh Internet satellite project, bypassing these asshats completely once and for all. I'd switch in a heartbeat, even if it was a bit more expensive.
The proposed SpaceX satellite network is in low earth orbit unlike traditional satellite Internet, so it should provide decent latencies (25ms vs 600+ms):
Unlikely. Even if Google were to go hard into the video space (unlikely but not impossible), they still wouldn't benefit from throttling/capping. It would just give users a reason to go back to their original providers. Furthermore we've already seen the governmental backlash when facebook tried similar in developing nations.
*I should clarify when I say "the video space" I mean original AAA content like Netflix is doing. I could be underestimating them but that's a LONG way from their market sweet spot.
If only there were a legal solution for such problems, something that any sane person would consider obvious. We could solve it by tomorrow 6pm, without a single satellite launch.
