Ruby, I wish you would stop grandstanding. Just because you enjoy your own lifestyle does not mean everyone would, and I say that with the deepest possible affection.
For most US broadband customers, there are one, maybe two options. However, it would certainly take a bite out of their profits if a boycott were organized wherein everyone swapped to dialup for a month. Would it happen? Probably not.
However, you appear to have missed the part of your linked article that points out that the FCC is far from powerless in this, and chances are they will simply reclassify broadband services to be more heavily regulated. According to the article, Comcast may well have not just shot itself in the foot, but might well have blown its whole foot off. So Comcast may have forced the FCC's hand. Perhaps they expected the FCC to compromise, or have to wait for some time before they swung again, but the FCC is saying that it doesn't have the time to fuck around in the courts, and good on them for that.
