I don't see what the problem is, they're giving away free masks, so what? If they didn't offer them then someone else would chastise them for hoarding excess masks. Damned if you do, damned if you don't, some people are just impossible to please.
The mask craze is stupid anyway, wearing a mask may offer some marginal degree of prevention from spreading the disease if the wearer is already sick, but it's unlikely to protect you from others. From the perspective of something the size of a virus is a mesh of gigantic gaping holes.
