Censorship, beyond what’s required by law, is doomed to fail.
The trouble with labeling something "misinformation" is that you also need to be one hundred percent right, forever or you need to be ready to make prominent retractions and groveling mea culpas. With this is mind, one ought to tread lightly on topics such as fast-moving science (especially the softer ones) and matters of policy recommendations. COVID was both of these. Yes, masks! No, don't use masks! Yes, masks. Yes, masks, haha you caught us we just didn't want you to buy up all of the masks. Yes, masks, but they really only prevent you from giving the virus to others.
My undergraduate was in the harder sciences, so it is not like I am some anti-science loon. I just think that acting with Total Certainty and If You Don't Agree You Are Killing People, on certain classes of topic, is a recipe for eventually being as believable as the numerous food pyramids which, once taken as gospel, now are simply shrugged aside.
