Hmmm, does your ISP have a TOS? If so, then by using that service you are agreeing to the idea that they have the right to set terms for your service, that connecting to their pipes can come with limitations. Branding it "internet access" doesn't convey any special protected rights to you, only that you can access the internet, in accordance with their terms. Your TOS probably doesn't even spell out that you will be guaranteed access to the entire internet. As long as they are providing you access to part of the internet, they have fulfilled their requirements of "internet access".
Now, that said, while I generally disagree with the Feds sticking their nose in any private business, I do agree with the idea of a free (as in speech) internet and if they do have to regulate net neutrality then so be it.
