The sneeze / cough / shout argument has some merit. The mask isn't going to do shit to stop you breathing things in, but it can attenuate the distance of a projectile droplet. How much that matters is not clear.
Once droplets get the mask wet, the virus go all the way through, dries on the outside, flakes off, and it's been spread around. Wet masks should be changed out and bagged immediately.
