You're misunderstanding me. My point is that a common anti-NN argument is "but Netflix generates so much traffic..." and I'm saying that argument is without merit.
I don't understand how traffic directionality affects peering. The path of routers between the client and the server handle all packets. The fact that the source is mostly from one size doesn't affect the load on the routers, they're still handling the same number of packets whether the traffic is symmetric or not.
They could send back a whole bunch of zero bytes to make the traffic symmetrical. They save everyone's resources by not doing that, yet somehow that means they should be charged...
The direction of the traffic is meaningless. What matters is the endpoint of the connection. ISPs should be happy to peer with anyone for traffic that has their users as an endpoint.
