Wearing a mask makes complete sense but you have to wonder why they were against masking early on"
There are a couple of reasons that come to mind quickly. One, of course, was the PPE crisis that has been discussed already.
Another, is that homemade masks can't be relied upon to protect the wearer. Covid particles are small enough to get through most home made masks, so telling people that wearing masks would protect them would have been be wrong. That fact hasn't changed. However, we now know that wearing masks reduces the risk that those who are infected will spray particles onto others, but at the beginning, the more urgent message was that we needed to social distance. That message still remains one of the most effective ways of stopping the spread.
