How is it net neutrality complicated ? ISP's business is to give reliable Internet access to paying customers and that's how it always worked (or supposed to).

How is it net neutrality complicated ? ISP's business is to give reliable Internet access to paying customers and that's how it always worked (or supposed to). Content providers like Youtube and Netflix do exactly the same thing on the other side of the pipe. My understanding is that big ISPs are seeing a market opportunity where they could charge both sides by using their user-base as leverage. Since both sides are already paying their Internet access they invent all sort of excuses to shift the story and make it look more complicated than it is.
