"Mirror mirror, on the wall: who is the most popular of them all?"

I don't know if any general-use tilesets show EN_US. I think you'd have to make a custom thing, which I don't know if you can even do with MapBox. Sounds like more work than a grift would want to put in.

Safer to watch it from the balcony than through a window, honestly.

If you look at the source OpenStreetMap data, the name for English is "Gulf of Mexico". If he wanted it to say "Gulf of America", they'd have to do some futzing with it to display EN_US first, when it exists.
