The researcher in the article you linked to still recommended masks.Yes, a report from the scientific community that it is aerosols.
Also pointing how useless ‘facial coverings’ are as a result. I don’t recall advocating for a respirator mandate for the vulnerable even in your dismissive reply.
Your description of "useless" does not appear to be shared by the scientist. If he meant to say "useless", he would not have endorsed them.
I do agree that masks are no substitute for proper ventilation or being outside. They are a moderate help.
