If the methodology in studies is flawed then it doesn’t actually show much of anything. Nobody is claiming anywhere that masks provide a guarantee against contracting a virus, what they do is reduce the number of viral particles that you inhale and reduce the chances of infection. There is also literally zero downside to wearing a mask, so this is a really weird hill to choose to die on.
