People keep complaining about this when it's really not a thing, and it has nothing to do with the USA.
For example in European-ish countries it's called Calcio (to kick) in Italy, Nogomet (leg) in Boznia/Croatia, mappa (ball) in Cyprus, labdarugas officially (ball-kicking) in Hungary.
There's another 8 or so countries where it's called another form of kick/ball/leg/something etc.
Finally it's called soccer in about 15 countries, of which the USA is only 1, where almost none of them have another variant of football.
