I wouldn't be surprised if in various post-mortems we will conclude that advising against face masks even though they do 'work' was a mistake. I'll be very surprised if we don't conclude that. I put this in the same category as abstinence-only proponents lying about the effectiveness of condoms. The really frustrating thing here is that mask shortages are not a fundamental law of nature. If you have a t-shirt, scissors, and rubber bands, you can have two reasonably effective masks in 5 minutes. And there are millions of people with sewing machines who would be happy to help out, as happened in the Czech Republic.
