Google announcement on X:

We’ve received a few questions about naming within Google Maps. We have a longstanding practice of applying name changes when they have been updated in official government sources.

For geographic features in the U.S., this is when Geographic Names Information System (GNIS) is updated. When that happens, we will update Google Maps in the U.S. quickly to show Mount McKinley and Gulf of America.

Also longstanding practice: When official names vary between countries, Maps users see their official local name. Everyone in the rest of the world sees both names. That applies here too.

How this will lower the price of groceries I have no idea.
