If the non-trivial-much-highler-than-netflix monthly cost of verizon's internet service does not cover the cost of verizon connecting their customers the internet, what the hell does it cover? I also don't understand why they are talking about "Review Shows No Congestion on Verizon Network", people are paying them for internet service, not verizon network service.
