A good analogy would be the legal ruling on whether bars and nightclubs could allow women in for free and yet still charge men at the door. The idea was that while women are good for business and a bar “rich in female content” will attract the paying men to come in while keeping out enough guys(who couldn’t afford to pay) to keep the content at a proper “male/female” ratio. The courts ruled that “ladies night” was discriminatory. We all deserve equal access to their business. ISPs want to charge more for you and I to access the internet(the guys) than they would for the big internet draws like the major media outlets(the girls) knowing that we will pay up. They reduce some of the traffic which is expensive(too crowded bar) but make up for it with the higher rates(the cover charge).
