So they knowingly "exaggerated" the effectiveness of the masks most ppl were using, and to cover their ass there has been - sans the CDC announcement - zero effort to update that narrative? And these are the same ppl and entities insisisting "trust us" and "trust the science"? This ^^^ isn't a conspiracy theory. This is what happened and is still happening. How am I, or anyone, supposed to truth that architecture?
