> So it's disingenuous to say that service providers (Google, Netflix), are extorting anyone.
I don't think anyone was saying that.
> With Netflix and Google, both were basically saying, "we're not going to pay you (Comcast/Verizon) for access to your network, because we're important enough that we shouldn't have to." They don't have their own ISP networks to exchange traffic at the same rate, all they have is their services, so they don't have anything to offer the ISP in return.
Generally peering agreements work on total bandwidth and generally you try to make it as balanced as possible, so there's no cost to either side, as traffic may traverse your network from the peer but not terminate there (it continues through another peer), and that's just a load you bear, but the other side has the same risk.
For an end service peering, that's not really as much of a risk, to my knowledge, so what you have is purely a win-win, where Netflix delivers content directly to your network so it's quicker, and you aren't using up peer bandwidth and backbone connections to serve that same content. In any market where Comcast/Verizon didn't have near monopolies over large areas, Netflix could easily charge for this access given their size and ubiquity. That some large ISPs are actually throttling the content only highlights the perverse incentives at play.
