The confusion is magnified by the fact that to achieve the results medical professionals achieve, you have to know how to wear them like they do.
One of the ways I read a certain now-infamous communication from a surgeon general was (a) we need the limited supply of n95s for medical staff (b) we think there are better measures the public can take to protect themselves and (c) we're not confident the public can wear them correctly.
(a) made sense, though there's always the temptation to think "maybe I too should have a few."
(b) can't get the virus if you're keeping away from people, or in a strict bubble. Same logic as abstinence/monogamy and STDs. Though the policy proved to be even less popular than extended runs of abstinence and monogamy, hence the inevitable interest in prophylactics.
(c) What? I was kindof insulted, personally. And thought that represented an insulting view of the public.
BUT after learning about fit testing, trying it on my own, and struggling to keep a consistent fit that passed a test.... yeah. I had to admit I was not a natural at wearing an n95. And as for the public, all of us have seen people wear masks sloppily, or pull them down to sneeze, or any number of other behaviors that entirely defeat the purpose. Who has confidence that most people would wear an n95 in a way that passes a fit test?
Of course, badly-fit n95s probably provide better marginal protection than well-fit cloth masks, so maybe they should be an acceptable public intervention when available, but I doubt they'd protect the public as well as they do medical staff that's learn to fit them.
Which makes the infamous announcement arguably correct, although it remains a communication failure. But then again, the more complex you make a communication, the more poorly it scales, and "masks work if you wear them correctly and here's how you determine this" might already be ineffective.
