Multiple studies show masks do help reducing droplets on exhale/speaking. You're late to this thread... multiple links contradict your judgement.
Two points.
1. Do those studies show how the infection rates drops if people wear/don't wear the masks outside? How much the infection rate changes? Any studies?
The studies showed less droplets in the air. You don't need to use physics to make the correlation that less droplets should equate to lower viral load.
2. WHO and CDC made several statements that masks don't help, only people caring of infected patients need to wear masks, etc.
This is misinformation.
The WHO did not say that "masks don't help"... read the PDF they put on their website, they say they do help.
CDC also updated their masks recommendation.
Conclusion. They really know little, constantly contradict each other. Pick the expert you trust and follow their guidelines. Then again, be ready to get completely disappointed, when your chosen expert makes a U-turn.
Practical data shows that areas that have higher mask usage has lower infection rate. Seems logical to me.
