A cloth mask does reduce the spread of aerlsols as well as droplets. Anything telling you otherwise is false and i will happily bury you in a dozen backing studies.
No it doesn't. The last year and a half is proof that masks played no significant role in reduction of infections. Bringing all kinds of studies doesn't prove anything since we effectively had the chance to witnesss the biggest study of all. Sure, it might stop some droplets. But a mask can never be as effective as a condom in stopping the virus. It s common sense. You can still infect or get infected. And that s the issue.
