I think your model of the network is too simplistic.

If A hosts a very popular service and B uses it and C's "quality of 
service" goes down, you are assuming that A is responsible and is somehow 
getting a free ride by others paying for externalities. But why isn't B 
responsible, since it is using the service?  And if B and C have the same 
provider, then perhaps the provider, D, needs to increase capacity or 
lower B's usage through technology (CDN's) or economics (bandwidth caps) 
or other means.
