  It is clear that the message in almost all that mask communication was that masks actually do work, but please save them for medical personnel... here are a few weak reasons why they probably won't help you that much anyway. And comparatively, they are way more critical for medical personnel. They should have just communicated it that way rather than trying to downplay effectiveness. Shortages abounded anyway.
