This is an interesting case and I (physics BA, now MD) welcome input from aerosol scientists @jljcolorado Better & smarter ventilation will keep us safer from C19 and future viruses.

The aerosol debate (is it a debate?) does not convince people cloth masks aren’t useful. If anything not talking about aerosols openly and clearly probably makes the public mistrust us all, and mistrust masks in total.

I have had people directly tell me this is why they don't wear masks. Masks let in air. The virus is airborne. Thus non-N95 masks don't work. It's also been complicated by studies that show that a majority of people who get the virus wear cloth masks. Correlation \= causation.

I think your example are good to show why we need to talk about this more, not less, including why cloth masks are good for source control, and not as good as PPE. The lack of authoritative and loud voices on this allows for confusion and misinformation.

Agree. It's not what "the public" concludes. Certainly not what I have seen. Instead, I have seen people open windows, watch how long indoors, and in fact double mask. I have never seen someone stop with masks.
