Interesting source. Here are some of the actual conclusions of that study (direct quotes from the study itself):
Without a face mask, it is almost certain that many foreign droplets will transfer to the susceptible person. Wearing a mask will offer substantial, but not complete, protection to a susceptible person by decreasing the number of foreign airborne sneeze and cough droplets that would otherwise enter the person without the mask.
Therefore, both the virus carrier and the susceptible person could consider wearing a mask to reduce the transmission and spread of the virus.
Furthermore, depending on breathing comfort, wearing multiple layers of masks could offer increased protection.
This study, which can be treated as precautionary, provides quantitative support to the guidelines proposed by the medical research community that wearing a mask and avoiding close face-to-face or frontal interactions as much as possible will help in preventing the transmission and spreading of virus particles, such as COVID-19, through sneezes and coughs.
That may be, I was pointing out that it's strange that this study was brought up to support OP's statement that masks don't work, given that the study says the opposite. I didn't bring up this study, and I can't vouch for its accuracy.

Oh, I didn't realize people thought they were 100% effective. Even N99 masks only filter 99% of particles.
