How is Netflix taking advantage of the ISPs?
They pay millions every month for their outbound bandwidth and Netflix customers pay millions every month for inbound bandwith. If the ISPs need to build up their infrastructure, then it should fall on the ISP’s customers. Netflix is already paying for big “pipes” at their end.
It isn’t Netflix’s problem that ISPs have consistently over-promised and under-delivered.
There is no motivation for the ISPs to play along. As far as they are concerned, their best customers just surf the web on low bandwidth sites. Some even systematically eliminate customers that regularly use high intensity apps for P2P or even USENET.
Most are even getting out of USENET entirely, and throttling whenever and wherever they can. There will be no charity to Netflix, here.
