I side eye a lot of these streetwear brands that charge exorbitant pricing. At the same time, the idea that individuals are supposed to just bend over and take it when their merch is looted/stolen doesn't seem like a solution either. It is possible to support protesting and denounce looting @ the same time..
With regards to the donation, I'm not pocket-watching but I have personally donated more than $50 so that is looking shaky if that is all he's done.
