Depending on what are you watching I guess. Everybody needs to be rewarded if they are providing you some service. Your service would be sitting in front of the TV and enjoying the show Imagine if you were they woodworking man and building the dinning tables and people would just come over and take them and never gave you a dime? I guess its not a best comparisson, but you get the point.
I am never paying for HBO, STARZ, or similar TV stations, as I find it expensive to order just one channel for a monthly fee, however everything you can find on Netflix, amazon prime, hulu, etc, I would recommend subscribing there and that way those shows get rewarded.
