English isn’t even the official language of the United States — we don’t have an official language.
Various states have official languages (19 states + DC don’t have any official language); of these states, English is indeed official, with a few states also recognizing native languages as official alongside English.
Of course that’s beside the point, as even calling this sort of racism “thinly veiled” would be far too charitable.
I really don’t think it’s the devs driving these decisions…
