As a cable subscriber, I expect that when paying for N Mbps of bandwidth, I'm entitled to N Mbps of bandwidth of the content of my choosing. If Comcast's pricing model needs to change to a cost-per-gigabyte model in order to cope with the increased quantity of data customers consume, so be it. But sneaking the costs onto Netflix's tab effectively shifts Comcast's costs to all Netflix customers, allowing Comcast to artificially lower their prices relative to smaller ISPs without the market share necessary to effectively extract rent from Netflix.
