I hate the name change too but it did go through official channels, so what else is a map provider supposed to do? Should they have also refused to rename Mt. McKinley to Denali? I mean, I'd actually be proud to see an overtly partisan declaration that they won't honor a single name change from this administration, but that's a much different matter than taking it case by case. I suspect the real reason the rename hasn't happened is that MapQuest's software simply isn't capable of doing it gracefully.
Also, hope you have a good adblocker when you use MQ. They are owned by bottom feeders of a sort that makes Bending Spoons look like the FSF.
