So you say that Netflix as a company shouldn't try to get the best deal they can they can when signing with an ISP? Interesting theory...
Any ISP signing a contract with Netflix should realize what a bandwidth hog Netflix is. If that incurs extra costs for the ISP it's THEIR problem. If someone downstream throttles Netflix because users on that ISP uses a lot of bandwidth it's still not Netflix problem, the users ISP has oversold their available bandwidth.
It's a fact that the internet provider market in the US lacks competition and is more or less monopolistic or duopolist with hints of cartel agreements. When a market is dysfunctional in that way someone has to step in and sort the mess out since it's obvious the market wasn't interested in fixing it.
And by the tone in your post you rather have a dysfunctional internet provider market that abuse and gouges it's customers every day than some weak regulation that will at least try to fix the worst problems.
And FYI, it's because of progressive world views that we have a modern society but you are welcome to stay in the past while moaning about the progressives wanting progress (because without progress things stagnate).
