Yeah, it really doesn't seem all that plausible that cloth masks do much at this point. Not only was there never good evidence for them working, the best ones only block something like 90% of virus-bearing particles. To put this in context current estimates seem to be that people infected with Delta produce 100-1000x the amount of virus that previous variants did; the effect of mask wearing is absolutely miniscule compared to that.
