Netflix pays for its bandwidth, like any internet service. If Netflix were to offer some ridiculous streaming option like 50k video, customers simply wouldn't be able to stream it because the customer is only paying its ISP for 10mbit or whatever. If the customer really wants this 50k video, it will have to pay the ISP to upgrade. In this way, the ISP is making its money off of Netflix already.
