I believe the "violations" people cite are very blown up, example being Comcast blocking bit torrent, they worked with bit torrent and made their service much more efficient, win win for everyone.
That being said I do not trust big cable companies, and that's why I don't share the "The free market will take care of itself" approach some republicans seem to have, which ignores there is no competition in some areas to begin with. I'm pro net neutrality, and am hoping some future law can ensure this without being inherently suffocating for ISPs.
