Sorry but this is ridiculous. In any language, we have different names for places than in those places’ native languages, and that’s perfectly normal. “Türkiye” is impossible for a native English speaker to parse - it isn’t even written in our alphabet. Are we to start writing Sweden as “Sverige”, or Kazakhstan as “ Қазақстан”? Should we start pronouncing “Paris” “Pah-reee”? We don’t do either of those, because we understand that languages have their own names for places, and don’t want to insult native speakers by butchering the pronunciation.
Rant over.
