And if you understood that. You'd understand why the messaging on masks changed. Early on, the focus was on keeping a person from inhaling the virus. N95s are required for that, and there was a massive shortage with healthcare workers the most likely to be exposed.
But with the discovery of asymptomatic spread, the focus shifted to what can masks do the help keep virus from traveling from an infected person.
So there has been no mixed messaging, just a lot of ignorant people propagating destructive misinformation.
