This is a good analysis of mask usage - 300 pages but from arguably the most trusted/reputable organization on the planet. So if we are screaming "follow the science" then these folks are a good place to start.
Respiratory Illness Analysis
Medical or surgical masks
Seven studies took place in the community, and two studies in healthcare workers. Compared with wearing no mask, wearing a mask may make little to no difference in how many people caught a flu‐like illness (9 studies; 3507 people); and probably makes no difference in how many people have flu confirmed by a laboratory test (6 studies; 3005 people). Unwanted effects were rarely reported, but included discomfort.
N95/P2 respirators
Four studies were in healthcare workers, and one small study was in the community. Compared with wearing medical or surgical masks, wearing N95/P2 respirators probably makes little to no difference in how many people have confirmed flu (5 studies; 8407 people); and may make little to no difference in how many people catch a flu‐like illness (5 studies; 8407 people) or respiratory illness (3 studies; 7799 people). Unwanted effects were not well reported; discomfort was mentioned.

So really reducing the fluidic conduit expression is the easiest form of reduction of transmission but it can not ever stop transmission completely....
So... masks help..
