I am surprised AT&T left the comment section open in their Public Policy Blog that this Comcast response links to: http://www.attpublicpolicy.com/consumers-2/who-should-pay-fo...
They get raked over the coals (and rightly so, IMHO), by people pointing out that they already pay for their bandwidth, so why should they pay twice (once through AT&T and once through the costs Netflix would have to pass through to them).
It really seems like AT&T and Comcast are complaining that people are actually starting to demand the full service that they pay for. It is really hard to take that argument seriously.
