I just watched that video a day or 2 ago. I was pretty surprised to see that, and I agree it makes no sense for the case of broadcast TV. My guess is it's a push from sports networks (90% NFL) and they'll arrive at some "compromise" to only turn it on during NFL and NBA games. Not only is it oppressive to viewers, but I think it's a terrible move for local broadcasters by actively blocking people who are already leaving/left in droves for the internet.
