Is there a polite non-obnoxious, non-shaming, (and non-violating social distance rules) to tell people in Costco that their valved N95 masks are not helping at all and they should find other masks?
That's just the official bullshit, brought to you by people who a short time before were saying masks were worthless. Really masks work both ways: they filter incoming air as well as outgoing air.

No, it's coming from
@zeynep who was also among the most vocal that masks were not worthless. -
She's worthy of respect, but I don't think she's ever explicitly said that masks don't filter on the way in, and it's such a silly thing to say that she probably wouldn't ever. Filtering on the way in is still helping with disease transmission.
