Eh, lots of countries have different names in other languages. In English, we call it “Germany,” not Deutschland. In Spanish, it’s “Los Estados Unidos,” not the United States. In English it’s “Wales,” but in Welsh it’s Cymru. Just 3 of hundreds of examples
They asked for being written Turkiye especially in English. In Deutschland we can go on calling their country Türkei because out turkey is called Truthahn.
I have no opinion on this, but maybe it just takes more time. I don’t hear anyone calling Chinas capital ‘Peking’ anymore, only Bejing, but that didn’t happen instantly either.
