Welcome to the free market: Supply & demand.
There is a demand, thus a supply appears. Let's weigh the choices of pirating. Free high quality commercial free content I can watch instantly as many times as I want. No DRM. Any digital content ever produced can be obtained
a cable service I pay too much for, with pre-set schedules, commercials louder than the program (which I'm now paying to watch) that I can't fast forward, pause, or rewind (unless I pay for it) and the content is locked into my cable box so I can't put it on my phone, ipod, ipad, or laptop.
Honestly, from a consumer business standpoint, it's a no fucking brainer.
