Well, if the broadcasters get $ for cable subscriptions, broadcasters have a reason to want you to subscribe to cable. Also, the cable companies really don't want you to get into the OTA habit, since OTA has many of the things you want linear TV for and goes together with OTT like peanut butter and jelly.
Do people think there is something ritually unclean about getting OTA television? I know that a lot of people that I talk to about my OTA setup seem to think I am doing something illegal.
