The email he said they are for sick people to wear and wouldn't help much against a virus - but would offer some defense against droplets.
"The typical mask you buy in the drug store is not really effective in keeping out virus, which is small enough to pass through material. It might, however, provide some slight benefit in keep out gross droplets if someone coughs or sneezes on you."
he recommended that the person who sent him that email not wear a mask, but bear in mind that was February 5th and we had 12 confirmed cases in the US.
And when the guidance changed he explained that it was because it had been determined that asymptomatic spread was high with COVID. Actually, it turns out presymptomatic spread is the culprit in most cases, not asymptomatic, but for all intents and purposes it means that a good percentage of the spread is from people who don't know they are sick. As such, healthy people are recommended to wear masks as if they were sick people.
If freedom is more important to you than safety, fine. But why make up stuff and intentionally misrepresent what people are saying? For example, if you don't want to wear a seatbelt, don't wear one. But don't try to make it look like seatbelts don't work with half-ass misrepresentations.
