Basically, yes. However, if we make a distinction between respirators (e.g. N95 mask) and masks (including "surgical" masks, which don't really have a meaningfully better FFE than cloth masks), then at least respirators offer some protection to the wearer, provided they also still minimize contact. But, in keeping with this distinction, yes, masks were never seriously scientifically supported. It is incredibly disheartening to see mask mandates still in cancer wards, despite these being mandates for (objectively useless) cloth/surgical masks.
