This is correct but I find it very confusing why this information (that masks prevent respiratory droplets rather than virus particles) wasn't more widely known during the pandemic. It felt like it was reported in thousands of news articles.

In the GPs case I suspect they knew what result they wanted to find and avoided any articles about how masks worked, let alone checking the scientific literature.

I spent a lot of time checking the literature and did better testing in my high-school classroom (as a teacher) than the CDIC did.

What is CDIC? How have you judged that you managed to do better testing than them? There have been a lot of tests of the efficacy of masks, not just from one organisation. Especially during the pandemic; there were many organisations across the world doing studies.

If you didn't manage to discover that the main benefit of lower grade masks is to restrict respiratory droplet movement then your literature search was very ineffective.
