Except that the cable company isn't the only game in town anymore. You can get internet through DSL, satellite, 4G, fiber, and the next generation of wireless technologies will eliminate the need for last mile cables all-together. They need to change their business model to account for that, but so far all they've done is try to lock customers in through restrictive distribution of content.
Right, I was using cable as a general term, but who (in the US) owns DSL? Phone giants like AT&T, Verizon, etc. Satellite, same issue, 4G, fiber etc.. is all owned by the large telco's and cable companies. Also, the hip small company that's out there to "battle the giants" is paying the giants for carriage because they can't install their own infrastructure. Those wireless technologies aren't here yet, and I'd argue it won't eliminate the last mile, and even if it does, there's the thousands of miles in between that are still being carried by infrastructure that has a cost. Content distribution is a whole different ballgame and the restrictions aren't usually put in place by the IP but the content originator. The IP, regardless of who it is simply delivers what content has been allowed.
