Is Verizon actively slowing the connection to Netflix.com itself or is the connection between Verizon and Netflix's provider (Cogent?) simply limited? In other words, are all Cogent customers suffering poor performance with Verizon customers? Because the former is wrong and demanding more money from a single company hosted on a service provider you have specific peering agreements with is extortion. The latter however, well, no one said there were unlimited pipes between every transit provider on the planet and if you're someone large like Netflix, sometimes you need to pay for transit on more than one provider to get the performance you need when your own provider can't or won't do so themselves. It has been like that for decades.
