Comcast has been fighting net neutrality for as long they've offered internet access over their wires. Finding loopholes in the existing law, illegally throttling bandwidth, making backroom deals with Netflix and Hulu, financing the so-called "Restoring Internet Freedom Act", contributing to politicians that support internet deregulation.
Comcast is just trying to squeeze another dollar out of you, and if they can pull it off without actually providing service, so much the better. Imagine if they started charging you extra because you watch too much TV. OK, that might not be such a bad thing...
