THIS. Its mostly about Netflix. Charge enough that it costs less to order Pay Per View than to use Netflix, then TWC pushes them out.
And this is pretty much what my ISP tells you if you call to complain about their 150Gb per month cap. "Use our on-demand services and it won't count against the cap." Same with their VOIP service (which I thought wasn't allowed). Bear in mind that their overage charge is $1.50 per 1Gb.
