@daas-yochid He lied about what? That masks are ineffective? Or that masks are effective? The guy made a public announcement that he made a mistake and after reviewing the evidence he’s changed his mind. Why would someone lie about that? And why wouldn’t you believe him?
I think there’s a lot more truth to that statement then, say, the claim that masks can cause people to have potentially fatal breathing problems. The former is backed by documented evidence, the latter is a dangerous fabrication being pushed on social media.
Masks work. Wear them.
