The mutual benefit still exists. Comcast benefits from peering with Netflix because it allows Comcast customers to access Netflix. Comcast is just playing chicken because they know their monopoly position allows them to hold out longer than peers with actual competitors.
> You're right, I'm just trying to disambiguate it from the net neutrality argument, which doesn't seem to actually be relevant here (as Comcast is treating all traffic through those links poorly, not just Netflix traffic).
The network neutrality issue is that Comcast is intentionally causing congestion on all the links that Netflix traffic could possibly use. The traffic for Comcast's own competing video service offerings don't have to traverse the congested links, nor does traffic from anyone who Comcast provides with a separate uncongested link in exchange for a toll or some other business consideration. That's practically the definition of a network neutrality issue.
