Of Course They Did
Of course they throttled Netflix. Of course they did. If I was running Verizon I'd do everything I could to create and maintain artificial scarcity across the board. Netflix is simply the most visible. I believe Aereo is also being throttled. As well as numerous web sites.
An investigation will turn up Nothing of Any Kind. Because every system administrator reading this knows there are countless ways to monkey with a content provider without leaving -any- breadcrumbs whatsoever. It will be the methodology used by the huge ISP's in order justify implementing Metered Billing as quickly and as pervasively as possible. Metered Billing is the real pot-of-gold for the ISP's. Almost limitless profitability.
I believe they are also using Net Neutrality as a red herring to further justify Metered Billing. They will first seem to fight, then seem to cave, on Net Neutrality, then use this "loss" as a further justification (the first being scarcity) to go to Metered Billing.
These are exactly the steps I would take if I ran any of these companies. The strategy is so patently obvious as to require a bribed and paid off lackey to miss.
