> The messaging on masks should have been that only n95 or better are worth the time

Which is simply rubbish.

Masks of all kinds will prevent transmission albeit with varying levels of efficacy. And most importantly they impact human behaviour in ways which prevent transmission.

Not to mention that N95 masks are more expensive which would have reduced its use by people who are poorer and are far more likely to spread the virus i.e. they are more likely to have multiple jobs, travel further for their job, work longer hours etc.
