Not sure if this works as an argument, but in this case Google added the new US name even in international versions of Maps as a secondary name. That does feel a bit odd.
I believe it is Google’s policy to show users official map labels based on the geolocation data of the user. If you compare maps between countries with border disputes, the one you’re “in” always shows all of the disputed territory as belonging to that nation.
But this thread is talking about how the label appears to third countries. In this case, we're seeing two names: a) a localised version of the 500-year-old, internationally established name b) another name that someone made up 5 minutes ago.
