I remember those changes well. I had my nice shiny FOTM Ice/Energy Blaster, then a month later the PvP changes happened. I was new to PvP in this game so it didn't piss me off, but I did not feel like going through the process of leveling and slotting a new character that I was mainly gonna use for PvP.
I think the person going into a PvP zone then asking and/or demanding not to be attacked is the primary person being rude. They are asking people to ignore valid rules, intent of a zone, and what the other people want to do. They are asking/demanding everyone accommodate them and what they want regardless of how the other players feel.
