Things like open beds in hospitals can change hour to hour and absolutely city by city, town to town, etc, I'm not sure what you were hoping to gain by calling the hospital and asking. That info could have been days or even weeks old by the time they heard of it as it was info from a friend of a friend. Being unmasked for a photo op is not surprising. Shortages are/were well covered in the news if you are in an area experiencing them, and wouldn't be if you aren't.
Here is the one from my neck of the woods:

At the end of the day, if
DCL has decided to have their CM mask again then it is what it is. I'm glad the info was shared so folks know what to expect on board, and expect it will quietly go away as quickly as it came once whatever reason they went back to it is resolved.
