They were wrong. At the time it was believed that most transmission was via surfaces, but that turned out to be very rare. (IIRC, 1 case in 1000 in a study from Ireland)
Cloth masks do work. Anything that can catch droplets works.
"Masks reduced viral RNA by 48% in fine and by 77% in coarse aerosols;
cloth and surgical masks were not significantly different"
