Some people have waaay too much free time and will have a bone to pick over the dumbest thing. Gariory probably said something to someone somewhere else that that person or someone else "on their behalf" took offence to and decided to do that as a form of "attack/protest" against Gariory. It's super dumb, regardless of the reason, but not much to be done about it without the culprit coming forth and explaining themselves.
