You've managed to argue with the individual phrases while missing the actual point. Tell you what, let's assume that you're right. The CDC is continuously reevaluating mask usage by the general public, but recommended against it due to fears of a shortage and/or hoarding. That being the case, please help me understand the following: 1) Why did the CDC change guidance on mask usage despite the shortage and risks of hoarding being, if anything, worse than before? If it was the controlling factor before, why is it not a concern anymore? 2) If they are continuously reevaluating policies, and believed masks should be used, why was the guidance not changed at any point in the last 10 years when there was no shortage or any particular reason to worry about hoarding? 3) Why is this a more parsimonious or plausible explanation than the one advanced in TFA, which is that they had a very high standard of evidence which they have relaxed somewhat in the face of a pandemic?
