I think an ad-supported site is a little different scenario. You pay for internet which then allows you to access sites not affiliated with the internet provider. Kinda like purchasing a car. It takes you places, but buy a car isn't going to generate any revenue for the places you go. They are independent.
With TV, I see it more like paying for food delivery. I am paying for someone to deliver what I want to my house. If they delivery person gets there then requires me to read a brochure before I get my food, that would be ridiculous. Yet that is exactly how cable companies work. They double dip by charging me for cable AND forcing me to have advertising, where most modern models use one or the other.
I have no sympathy for the companies saying I am doing something illegal by skipping commercials. I paid for the television service. I shouldn't have to "pay" again by watching your stupid, repetitive ads.
