Specific criticisms please.
https://www.pnas.org/content/118/4/e2014564118 An evidence review of face masks against COVID-19 Abstract The science around the use of masks by the public to impede COVID-19 transmission is advancing rapidly. In this narrative review, we develop an analytical framework to examine mask usage, synthesizing the relevant literature to inform multiple areas: population impact, transmission characteristics, source control, wearer protection, sociological considerations, and implementation considerations. A primary route of transmission of COVID-19 is via respiratory particles, and it is known to be transmissible from presymptomatic, paucisymptomatic, and asymptomatic individuals. Reducing disease spread requires two things: limiting contacts of infected individuals via physical distancing and other measures and reducing the transmission probability per contact. The preponderance of evidence indicates that mask wearing reduces transmissibility per contact by reducing transmission of infected respiratory particles in both laboratory and clinical contexts. Public mask wearing is most effective at reducing spread of the virus when compliance is high. Given the current shortages of medical masks, we recommend the adoption of public cloth mask wearing, as an effective form of source control, in conjunction with existing hygiene, distancing, and contact tracing strategies. Because many respiratory particles become smaller due to evaporation, we recommend increasing focus on a previously overlooked aspect of mask usage: mask wearing by infectious people (“source control”) with benefits at the population level, rather than only mask wearing by susceptible people, such as health care workers, with focus on individual outcomes. We recommend that public officials and governments strongly encourage the use of widespread face masks in public, including the use of appropriate regulation.

When the hysteria and anxiety around getting the disease is 99% WORSE than the disease itself, there is some sort of disconnect. I'm talking in the low risk category. People under 60 with no comorbidities.
Could have been Cuomo/deblasio, here in NY and their: "It's like fighting air, we cant control it" comment Call for 50,000 ventilators Call for aircraft carrier and javits center to be used as hospitals. People didnt use their common sense. They wore masks outside because they were told to. Many looked down on others as "doing the wrong thing for the country". Now CDC says it fine. Well actually there was never a risk of contracting it outside. There was 100 cases attributed to a Singaporean construction site that were miscatagorized. Believe half of what you see and none of what you read or hear. Rely on what you know to be true. The same thing happened in 1918 and we didnt understand the science behind, but we've acted the same. Wait until these roaring 20s pass, to see how we really fared.

How would I "know what is true" about a complex (and novel) infectious disease, when I am not a scientist by training?
It's sure easy to be smarter than other people with the benefit of hindsight.

Conversely, we were told from the very beginning to listen to the experts. How can one be an expert in something for which very little is known? The "experts" (WHO) told us there was no evidence of human to human transmission of Covid. So how do you determine what you believe and what you don't?

Question for the people who resist wearing masks around others:
When you sneeze or cough, do you cover your mouth? Why or why not?

I wear a mask most of the time, but I'll answer the question. When I sneeze? Yes, and I turn my head away from others as well. When I cough? No.

Your appeal to authority mantra is a straw man by the way. I am not suggesting anything is true simply because someone in authority said it is. By your logic nobody could ever cite to any study.

If you say something and I point out it's inconsistent with Einstein's theory of relativity, have I only appealed to authority?

Science changes constantly, and at least reading the article suggests they did a really deep dive and critical reexamination of the data. If there was bias, financial self-interest, etc. that would certainly be a factor to consider, but I don't see that.
