The contempt for the general public from these people bordered on the perverse. How can they sleep at night? "We acted with the best information available at the time, and followed the scientific consensus to make our policy". Not even close to the truth, but maybe it helps a bit.
The hypothesis in the article was that the cloth captures droplets/water vapor that is carrying virus. And then it's captured there for you to continually suck it out of the cloth when breathing. Without a mask it would've drifted away.
