Also, masks have this "side-effect" of dehumanizing wearers (no doubt something the government benefits from), by making everyone's faces uncrecognizable, and as we all know, human's faces have the most expressive features that define a person.

Furthermore, they muffle & de-individualize your voice making you sound generic and quiet, which has a psychological effect on your ability/desire to voice your opinions.
