that initial “don’t use surgical masks” statement was because hospitals were already facing shortages, and a rush on the supply would have caused massive widespread longstanding shortages. Basically, the hospitals needed disposable masks, so the CDC told people not to use disposable masks.

That makes it worse that they said/implied masks won’t protect you, not better. If CDC public health statements are driven by an intention to manipulate public behavior rather than disseminating the best available info about what is true, that means that those statements are unreliable and can’t be trusted, regardless of the good they are hoping to do by trading their long term credibility for temporarily adjusting purchasing habits.
