Free-market types have been rallying behind Comcast and against Netflix for some time now. For the sake of context, the debate is over whether Comcast should be able to "throttle" access to Netflix across its Internet service. Netflix, hosting streaming video, absorbs an incredible amount of broadband Internet access that can ostensibly stress Comcast’s infrastructure. Those of a more conspiratorial bent cite Comcast’s desire to protect traditional television from the Internet upstart as the reason behind throttling Netflix.
The aforementioned free-marketers have been using some variation of the argument that Comcast can do whatever it wants with its wires. Or interconnected tubes. Or whatever infrastructure provides the Internet. Further, Comcast should be free to price its service in any way it desires assuming the market can bear those prices.
