If I am a paying customer of an ISP, I sure would expect them to get me the content I want at a reasonably high speed, even if that means they need to bring up additional capacity.

You could say Verizon is overselling their bandwidth to customers and that's why they have degraded connections to Level3. Is it not Verizon's obligation to their customers to upgrade their connections to handle what they've sold to their customers?
