I think this, like many cases, was a perfect storm of lack of information, good intentions and individual profit mongering. Medical masks have proven overwhelmingly effective in stopping the spread of airborne diseases like COVID.
Knit/cloth masks however barely did a thing. We were in a situation where we heard wearing masks was beneficial, and often times required in certain areas, but no restrictions around the _type_ of mask worn. In fact with the supply chain issues that were being faced the majority were unable to acquire N95/KN95 masks during critical periods.
Regardless I’m not going to ever look down upon people who did what they thought best in trying to stop a pandemic.
