Rules applied to the Block C Verizon spectrum by the FCC.
I section (b) it states that
"service on spectrum subject to this section shall not deny, limit, or restrict the ability of their customers to use the devices and applications of their choice on the licensee's C Block network, except: (1) Insofar as such use would not be compliant with published technical standards reasonably necessary for the management or protection of the licensee's network"
roughly translates that they are allowed to limit if the network is compromised.
BUT!!!!!!!
the technical standards specify that in (c) "For purposes of paragraph (b)(1) of this section:
(c2)To the extent a licensee relies on standards established by an INDEPENDENT STANDARDS-SETTING BODY which is open to participation by representatives of service providers, equipment manufacturers, application developers, consumer organizations, and other interested parties, the standards will carry a presumption of reasonableness."
roughly translates that the measures to which they limit customers MUST be carried about by an external organization and not by VERIZON's INTERNAL DIVISIONS.
Therefore, it is unlawful for Verizon to Self Regulate it's own bandwidth without consulting an INDEPENDENT and EXTERNAL source of measurement to VERIFY that a Customer is IN FACT causing a decrease in network performance per the amount of data used per tower by portions of customers subscriptions. In other words, Verizon needs to offer open access to all it's customers by and independent organization that discloses your subscriber data vs. all subscriber data including the percentage of your data that is affecting the performance of the tower's throughput. This is Verizon's attempt to place loose sanctions on customers unbeknownst to themselves that they have the right to know exactly why limits are being placed on them.
Following Tom Wheeler's letter to Mead, Verizon justified it's actions by stating "Verizon's network management practices are no different from the policies of other wireless operators."
THIS IS A LIE. Verizon is the only carrier that voraciously seeks to kill all unlimited data plans. Verizon is the only carrier that won't allow subscribers to get subsidized phones without loosing they're contract. This justifies the cost savings to the customer for having unlimited data on the part of the carrier. This stands as legal grounds for a class action lawsuit.
