Nothing about the biology of the virus or our discovery of it has changed in the past few months that would lead us to believe that masks are somehow more effective against it than they are against the spread of other respiratory viruses.
Masks don't work, after being made mandatory in the UK, cases went up not down. LINK
The CDC, as late as May, was citing the 10 randomized controlled trials that showed "no significant reduction in influenza transmission with the use of face masks." LINK
The Centre for Evidence-Based Medicine at Oxford also summarized six international studies which "showed that masks alone have no significant effect in interrupting the spread of ILI or influenza in the general population, nor in healthcare workers." LINK
When Dr. Fauci spoke so assertively against universal mask-wearing early on in the epidemic, it was clearly based on this knowledge. "There's no reason to be walking around with a mask," infectious disease expert Dr. Anthony Fauci told "60 Minutes" on March 8. He went on to explain that masks can only block large droplets, they give a false sense of security, and they cause people to get more germs on their hands by fiddling with it. Those facts don't change with time. LINK
Surgeon General Jerome Adams punctuated this point about the counterproductivity of wearing masks in public.Adams said that based on a study that shows medical students who wear masks touch their faces 23 times more often, one has to assume that "wearing a mask improperly can actually increase your risk of getting disease."

A 2015 randomized clinical trial from the University of South Wales testing the effectiveness of cloth masks among health care workers in Hanoi found that the poor filtration becomes a conduit for moisture retention. Researchers found a high rate of infection among those workers presumably because "their reuse and poor filtration may explain the increased risk of infection." Can you imagine how much worse this is in a non-health-care setting where reuse and cross-contamination are rampant? LINK
There has been no RCT to disprove the science since Covid-19 started. NONE. If you're ignorant, a RCT is a Randomized Clinical Trial.
If you can't point to a RCT to prove masks work, you are a science denier who has bought into a political like meant to condition you to be more controllable.
