Maybe they genuinely did believe that masks do not work. If the believe is that COVID spreads simliar to the flu that assumption makes sense. See https://wwwnc.

See https://wwwnc.cdc.gov/eid/article/26/5/19-0994_article https://wwwnc.cdc.gov/eid/article/26/5/19-0994_article We did not find evidence that surgical-type face masks are effective in reducing laboratory-confirmed influenza transmission, either when worn by infected persons (source control) or by persons in the general community to reduce their susceptibility The problem is that it is very hard to assess the real effect of masks, because they are always a part of a broader range of measures. The infamous Danish study is rather inconclusive and there are no other trying to measure the direct effect.
