What if Comcast's network is built around the idea that traffic is exchanged relatively equally? They put in gigabit switches everywhere, a nice fair balanced network.
Then Netflix comes along, and suddenly 35% of Comcast's customer traffic is all going to a handful of Netflix DSNs? Suddenly Comcast has to redo the whole connection. They have to buy top-shelf hardware just for Netflix.
I don't know if this has happened, but it's an interesting thought experiment to see how "just one company" could place disproportionate burden/cost on the ISP, as compared to the case where traffic travels to & from many different entities.
