Why wouldn’t the CDC publish guidance once it is ready, which the media can than report on? The mere coordination (and normalcy thereof) is exactly why people view these policies (gatekeeping) as nefarious.
Or you issue an embargoed release, allowing responsible 'spreaders' to get their ducks in a row, and then cometh the hour, cometh the copy-edited verbose well referenced pieces.
The latter is far better than the former.
From a practicality perspective it makes sense. From a propaganda perspective it’s chilling.
