I think conspiracy theories should be seen as a symptom of low quality education, and that makes it a big deal.
Of course the dumbest of us will fall for more theories, including the more incredible theories, but to pretend like any one person is immune is to ignore the step 1 of a 12 step program.
The people at Star Slate Codex supposed that this was to limit a run on masks.
Dr. Faucci just last month admits, yeah we lied about it at the beginning to prevent a run on masks.
The conspiracy folks in this case were correct. I am not including myself in the echelons or intelligence the SSC provides, but smart people were able to suss our this was a conspiracy.
Whilst I'm sure there's probably something in it, it's definitely not always the case.
