To soften this slightly - it's been within my lifetime that my social circle has moved from calling "Columbia" Colombia, "The Ivory Coast" "Cote d'Ivoire, "Burma" Myanmar (yes I know this one is actually more contentious than it first seems) and "Kiev" Kyiv. I think it's reasonable, where naming reflects some historical injustice or genuinely represents how the people of that country would wish to be perceived abroad (c.f. "Ethiopia" rather than "Abyssinia" - although, working from Herotodus here, I've never been terribly sure how much of a straight upgrade from "Hell-land" to "the land of the burnt-faced people" really is), to take that into account as language naturally evolves over time.
I just don't think Erdogan (who, ahem, I don't like) has the right to dictate that process, particularly for a change that, as far as I know, reflects no historical injustice, is difficult to spell on an English-language keyboard, and sounds almost identical. I also don't think Erdogan's nomenclature reflects any widespread desire among workaday Turks to change their name in another languages, though I could be proven wrong on that!
