Fact is that ISPs make money because of Google, MSN, Hulu, etc. If the content providers didn't provide content, there would be no need for the ISPs, now would there? The thing is, there's no bandwidth problem really, at least, not one they didn't create themselves. They've been over selling their bandwidth for years, and all of a sudden people found ways to make use of the bandwidth they've been paying for and the ISPs are freaking out. ISPs have always assumed that not everyone would be making full use of their bandwidth at any given time, so they could sell 10Mb steams to 20 houses on a block and simply connect them all to a 100Mb pipe. That worked for a while, but then people discovered P2P and video streaming, and all of a sudden all 20 houses wanted to make use of their 10Mb bandwidth and oops, they could only get half of that. The ISPs didn't want to admit they were over selling their bandwidth, just like airlines don't like to admit they over sell their flights, so of course they have to blame P2P and then NetFlix and Hulu and their "greedy" customers.
But anyway, there's more to net neutrality then that. The thing is that ISPs are also content providers. Which means it really has nothing to do with bandwidth because the bandwidth is available. See, if you decide to watch a movie from a competitor, then the bandwidth gets real tight, so you'll need to pay extra for the ISP to send a guy out and stretch out those pipes for that video to fit through. But before they do that they'll also tell you that if you watch that same movie on THEIR service, well, those pipes can be opened up at for a much smaller fee!
In other words, net neutrality enforces a free market. ISPs can continue to provide content, but they should not have an unfair advantage over other content providers who are not also ISPs. This makes it fair for all content providers as they will have access to all the customers. But the good news for customers is that they have full access to all content providers. The alternative would force you to not just pick your ISP, but what content you want as well, as one would determine the other, and there's no way you can tell me that's a good thing. At least, not for consumers.
