The US does not control the majority of the Gulf of Mexico. It cannot "change the name" of it any more than it can change the name of the Moon.
The executive branch has decided to call it something different than its internationally accepted name as a political stunt. Google could just ignore this, but instead they chose to obey in advance.
I mean I agree that it’s stupid, but my point was that there are protocols in place to handle this already.
If the US government says it’s the name of something, then it’s any map company’s job to display the valid name of the thing to the users in that country. They still show “Gulf of Mexico” to users in other countries.
