Right. Which is why we saw a great many "virologists" (who are not "maskologists", btw, so I'm not sure where we get this idea that they "work on masks" [1]) blindly assert that it didn't matter what kind of mask you wear, then for a long time defended the silly notion of a 6-foot rule (remember "ballistic droplets"? I do!), then said, "OK, cloth masks probably don't do much, but 'swiss-cheese model!'", and so on and so forth. Literally anything than just be intellectually honest about what the data says.
This entire debate has been insipid, and OP is correct: a great many people who should have known better shifted their brains into neutral and allowed slogans to drive the conversation. The entire point of the linked article is that the CDC has historically used crap studies to make causative arguments that wouldn't work in any other scientific debate.
[1] ...and let's not forget people like Jeremy Howard (philosophy major; Kaggle guy) and Zeynep Tufecki (librarian) somehow get cited as 'mask experts' and publish total gibberish in PNAS and other high-profile journals, despite having zero relevant experience. Expertise is a slippery concept when the speaker makes an argument you like!
