Verizon originally sued the FCC because of the FCC's Net Neutrality rules. They sued on the grounds that the FCC didnʼt have the authority to enforce the Net Neutrality rules. The implication, of course, is that they preferred to have the free market settle any such issues. So now,
So, Verizon isnʼt a fan of Netflix telling its customers just how bad it is. This is a well documented problem. It got so bad that Netflix had to bribe Verizon to allow Netflix to pay for its own transit and to pay for running an interconnect to Verizon. All Verizon has to do is connect to Netflix with a sufficient amount of bandwidth to fulfill their customer's requests and route that across their own network. Apparently, Verizon isnʼt even will to do that after being bribed.
Netflix is rightfully fed up with the situation, so they are doing the only thing that is left to them, informing their customers of the problem. Now that Netflix is letting their customers know that Verizon isnʼt fulfilling the service that they are paying for, Verizon is threatening to sue. Verizon is threatening to sue Netflix because Netflix is letting Verizon's customers know that Verizon isn't fulfilling their commitment to their customers. LOL.
This is exactly what Verizon was asking for. Now that its been revealed that they are willfully disregarding their commitment to their customers, instead of fixing the problem they are threatening legal action against the people revealing the problem. Its the perfect case to show why we need Net Neutrality.
