Without comment from Microsoft, I'm not sure if Bing Maps showing "Gulf of Mexico" exclusively is a political statement or a reflection of how frequently the service's information gets updated. I have reached out to Microsoft about the Gulf of Mexico name debate and how Bing Maps is updated.

Following President Trump's directive, Apple Maps has renamed Gulf of Mexico to Gulf of America. This change aligns with updates from Google and Microsoft.

Apple has changed the name of the Gulf of Mexico to the Gulf of America on its maps after an order by President Donald Trump was made official by the U.S. Geographic Names Information System.
