I'm actually shocked that so many people are on the side of the Blue Poster. While I'm not going to get into whether the dude deserved it or not, it *was* very unprofessional of Ornyx to say what he said, whether you liked it or not. People are always bashing on Blizzard, just like any other game company. Out of so many people, why did this ONE guy get singled out?
"The customer is always right" sort of fits this situation. If a restaurant gets your order wrong, whether it was their fault or maybe you didn't specify what you wanted perfectly, they're always going to replace your food and get it right.
Paying customers, whether right or wrong, expect that kind of service, whether its in a restaurant or on a video game. Armorying that dude and calling him out for thousands (or millions) of people to ridicule him was wrong.
