As has been pointed out and discussed on this thread and previous ones, and also discussed just about everywhere it is possible to imagine, there is no one single perfect modality that can defend against this virus 100%. It is well understood and has been for probably decades that many defences have to be layered on top of each other to overcome the weaknesses of any one of them. And so now you're discovered some obscure piece of research, whose immediate real-world relevance may not be apparent, that there may be occasions when masks are not perfect.
Well no sh*t Sherlock.
If you had just presented it as an example of how masks can sometimes fail, as part of a wider discussion in how to use available defences, well that would be kind of ok. But instead you intro the post with "So face masks might not be effective." In what sense is this not trolling?
IF the study is accurate, then we should be concerned about mask efficacy. One point of the article flagged that people may go into crowded situations thinking they're safe because they're wearing a mask, and they're not. It won't protect them. Rather than attacking me, you ought to check your behavior to see if you do these things and should take more precautions. Rather than trolling, I may have saved someone's life.
