They probably felt they were respected like crap by the vendor. When one party has a disagreement with another, and there's a clear and obvious disparity in some kind of standing (be it social, financial, racial, age), the party getting screwed over may feel they need to take action against this or have no trouble gaining confidence to stand up against a perceived injustice, since they're fighting two battles for the price of one. It doesn't matter if the second cause has nothing to do with anything, such as if the difference is only perceived or didn't matter in the situation. Whereas in actuality, the other company in question is likely simply trying to rip off everybody equally (equally, in other words, meaning as much as possible.)
