I think the idea of effective mask use has withstood sufficient criticism to warrant spreading aggressively, both to the public as well as experts in the field. It may be a mistake, but compared to no mask at all (risk of infection, barriers to reentering society) it is hard to see it being a significant mistake. The potential upside is significant. We may have a relatively cheap and safe countermeasure within reach.
