Coronavirus Surprise — widespread use of masks is known to make a statistical difference.

Which is it; Wide spread or in labs?
Wide spread masking does not make a difference. If you have an actual study, Not a health organization reference, but an actual study, I would love to read it. Again, not an observational or anecdotal study, something peer reviewed and robust, that I could use in my practice.
Lab use of masks is not wide spread use. I use mask when suctioning patients, and they work under those circumstances. Of course I use an N95, not the crap on my face right now. And a face mask, because who wants that splashing on your face or your eye, or anywhere else? So, yes specific, procedurally appropriate PPE is valid, functional and totally supported by me. However, I do not use my hazmat suit to go shopping, only for hazmat appropriate events.
Seriously, if you have the study, I want it. My health region doesn't have it, none of my peer reviewed platforms have it. I have access to one out of Vietnam that states non-medical masks (the blue ones) used as recommended, double the likelihood of catching whatever you are trying to avoid, if it's aerosolized, and that cloth masks increase it by a factor of 13. Scary. Latest data from my region is that "there is an associated increase in transmission from cloth masks due to poor storage and decreased rate of mask changing". Something I brought up 6 months ago, to no avail.
