The problem is ISP's have a monopoly. In a lot of countries there are only 1-2 options on what you can get. Also a lot of the fibre, cable and telephone lines they put in were payed by government taxes etc so I don't feel bad when the government regulates how the ISPs can charge for their network.

A lot of these companies want to double dip on services like Netflix because they directly compete with their cable offerings. Netflix already pays for their bandwidth just like any other company. If the ISP's want to charge more for data - sure.. go ahead.. but treat everyone the same.
