People were told last year that home made cloth masks were perfectly fine. I applaud skepticism at new claims, made without scientific backing, that now not even one mask is enough. My guess is that in order to increase the number of people wearing masks, they're trying a new scare tactic: maybe you should wear 2 or 3 masks. Maybe they hope that will cause people to wear at least one. Gotta herd the cattle somehow, I guess.
