The article tries to make the point that Netflix was trying to shift the cost of paying for bandwidth from themselves to Comcast by rearchitecting their peering arrangements in such a way that they benefited from settlement-free peering arrangements. But they just admitted above that it's usually the edge ISP who pays for traffic. It's obvious that the company rearchitecting their peering in an attempt to shift costs is Comcast. Comcast is (indisputably) an edge, almost entirely consumer-facing ISP. They can refer to parts of their network as a "backbone" however and whenever they like, but both Comcast and this article are using the term "backbone" simply as a way to try to equivocate their contractual relationships with classic transit providers. But as the article indirectly explains, this norm exists largely because for classic transit providers load generation is symmetric--transit providers with a good mix of customers are similarly situated in terms of economic position, and it's cheaper to minimize bookkeeping with settlement-free arrangements. But calling part of Comcast's network a "backbone" doesn't magically make Comcast's ingress and egress traffic symmetric. Yet the argument in the article is predicated on people making that erroneous mental leap. And as the article helpfully points out, when usage is asymmetric it's the edge ISP (on both ends) who ends up paying the bill. Thus, following the logic of the article as well as real-world practice, using settlement-free peering would normally be to Comcast's _benefit_! It also follows that because it was Comcast who rearchitected their network (if in name only) to shift costs, that it was Comcast maneuvering strategically in the regulatory space. That doesn't mean Netflix wasn't making regulatory moves, but if so I'd characterize that as Netflix calling Comcast's hand at a time & place of Netflix' choosing rather than waiting around for Comcast to show its hand. In any event, from a purely business standpoint, no way would the _potential_ benefits that might accrue to Netflix be sufficient to justify such a change in transit and CDN providers. Plus, this all ignores the fact that Netflix made the same free direct CDN peering offer to Comcast it did to every other ISP, which would have cut Cogent and Level 3 out entirely. It's just that Comcast rejected that offer; it wanted to be _paid_ for the peering! And they also rejected alternative offers to add more settlement-free ports with Netflix's transit provider. And Comcast's logic was precisely the specious argument that Comcast, purely by dint of how they referred to themselves, was situated like Level 3 or Cogent--a middle-man transit provider--rather than like, well, Comcast. But that's patently preposterous. Of course, Comcast should be free to require payment to peer directly with Netflix. And they can be free to reject offers of more settlement-free ports with transit providers. And I guess they're free to lie (as long as the FTC doesn't mind). But at the end of the day they shouldn't be allowed to freely sabotage net neutrality using their bogus arguments, mischaracterizations, and outright lies.
