True, though I have no idea what the AP style guide (assuming that’s what they follow?) says on the topic.
As of January of this year:
“Someone queried the Associated Press Stylebook to find out whether AP has accepted their as a gender-neutral singular pronoun, to which the editors of the stylebook replied no. Testy Copy Editors commented on Facebook: “AP holds the line, for now, against the idiot epicene.”

The singular ‘they’ is apparently popular with homosexuals, feminists, and homosexual feminists.
Let’s all agree that we are doomed, regardless.
