I can't imagine that's at all true, it just probably doesn't register for you because it's not at all a big deal. I'm in Boston and I still see plenty of people regularly masking. A minority to be sure, but still substantial. And I even sometimes do myself if I feel a little sniffly, just to be safe. At the end of the day, it's shocking how many people are infantile little bitch babies about wearing a fucking mask.
