Having had to deal with verizon, I can vouch that this is true.
At some point you reach a company that's large enough that they must cooperate because they want to remain in business of being an actual responsible ISP.
And then there's Verizon, who can safely ignore any ISP etiquette because they have a de-facto monopoly.
