Messaging needs to be consistent and err on the side of caution... this was the exact opposite of both of those things.
SARS-CoV-2 is actually not that unusual – the mRNA COVID vaccines that have been developed are based on the spike protein that is common to all "coronaviruses" (hence the name) and was previously isolated from SARS-CoV-1 (i.e. SARS). At the very least we knew it was a coronavirus early on, so there is no reason you wouldn't assume it was respiratory in nature, just like SARS was.
> This is a coronavirus, just as SARS was before it. This one seems both more lethal and more contagious than SARS, so we are recommending everyone wears a face-mask (even one you've made yourself) when you go to any public place until we understand more about the virus.
etc. etc. etc.
Not "no need to wear a face mask".
This also to a large extent fuelled the anti-makser movement you have trouble reigning in now. Absolutely moronic.

And most anti-maskers are against it because of government overreach. Unrelated to science.
A third party has emerged. The "we'll believe and parrot anything because it's what we're told".
They act in the following realm (whether they are aware or not): Cotton/cloth masks don't work. But it qualifies as a mask so checkbox! Moral superiority is on my side whether science is or not doesn't matter.
Fauci lied (and admitted to it) that masks weren't effective and suggested that the average person should not wear them.
To be fair, I heard the whole medical community here (I'm in one of the largest medical centers in the world) laugh and scoff at normal people wearing masks (because they weren't trained and it isn't effective).
And now we have no N95 for the general public and idiotic cloth masks (that don't work).
So it turns out they weren't far off I their scoffing... But for the wrong reasons.
Now we see them (and other anto-science) normals flip and ignore the data on bad masks. "Something is better than nothing". False sense of security and just more lies and moral superiority.
The problem has always been that this disease is very unusual in many different ways. This has quite understandably caused many best efforts at estimating it's behaviour to turn out to be wrong.
