Yea, I mean, good for the CDC, but good grief. They really come across as a tool of the Executive branch in all of this. (Not this decision, but the entire course of the pandemic.)
Also, can't wait for people to conflate the new CDC guidance for some sort of federal law mandating that private businesses cannot require customers to wear masks. People will struggle to differentiate the two, at least when masklessly lying about having been vaxxed. On the other hand, maybe a substantial number of people will lie so much about being vaxxed that they just say eff it, might as well make it official.
