In this case, remember that there was a time when people thought bacterial infections, like cholera, or parasitic infections, like malaria, were spread through bad smells in the air.
Unfortunately there are scientists who overgeneralize the lesson that bacteria and parasites are not transmitted through the air into a dogmatic belief that nothing can spread through the air, even viruses, and those sorts of people were in charge at the WHO and CDC.

It took domain experts two years to force those in charge to accept the truth that infected people do emit Covid into the air when they are just breathing normally, that the Covid they emit floats in the air for hours, and that people who inhale the virus do get infected.
Which is why it's unwise to censor everyone who doesn't toe the party line. Not just illegal, unwise.
