The same article then also goes on to reason why this doesn't seem to be the dominant way of transmission outside special circumstances (like ventilation).

I don't have a background in this topic at all, but apparently actual airborne viruses are really small: Measles is about 200 nm and Influenza about 100 nm in diameter, while Sars-Cov-2 is about 1000 nm, so 5 to 10 times the diameter and thus 100 to 1000 times the mass.
