But..
The Netflix/Level3/Comcast dustup was not a net neutrality issue. It was a peering disagreement. Comcast pays Level3 to be a transit provider, so they pay to connect to Level3's network. Traditional CDN's such as Akamai and Limelight pay Comcast in order to get a direct pipe into Comcast's network. Level3 in the meantime was charging Netflix as a CDN since they already had a direct pipe into Comcast's network as a transit provider. So in essence Comcast was paying Level3 to act as a CDN as opposed to the other way around.
While Level3 quickly screamed "Net Neutrality" when Comcast wanted to fix the agreement, that was just a smokescreen for a peering issue.
