Well, maybe because this is just an empty symbolic gesture made exactly to trigger progressives and let the MAGAs cheer about their “victory”.
Google maps uses whatever the name of the feature in question is in the language of the user. For me, it’s not “Gulf of Mexico”, but Golf von Mexiko, and if you visit Europe (as an English user), you’ll see Munich in Bavaria in Germany, not München in Bayern in Deutschland, as would be correct.
