"Condemned". The distinction between condemn and damn seems to go back to Latin, if not further.
I'm not sure it should matter what one particular authority decides, in terms of language use. People, including people writing administrative documents should be free to write in the manner that feels most comfortable to them. If this creates a political problem, the political solution is the ballot box and altering the education or hiring policies.
Customary criticism is fine, but it makes no sense to say "you shouldn't say foo because some organisation that shouldn't have authority says you shouldn't say foo"; instead, you should have some direct reason why foo is problematic.
Your criticism shouldn't be circular either, for instance "you shouldn't use 'singular they' because 'they' is plural" is completely, aside from being historically wrong, ineffective as criticism, since it is merely because of the incorrect description of the word as "plural" by some authority that you believe it to be plural, whereas most people use it regularly to refer to a non-specific person.
