I read the abstract of the article and learned 

(1) the authors didn’t say NOT to wear a cloth mask to prevent community spread, they actually encourage it, and

(2) they are pointing out there is no research to prove a cloth mask is as efficacious as an N95 mask in a MEDICAL setting, which is common sense.


The sad state of science in public discourse today is to dumb down topics into simple for/against emotional feelings instead of proceeding through the conversations on common-sense fact-based grounds.
