It's a bit more complicated than that. It is also quite rude of you, where you not to not accept that other people write using other letters have have other abilities in terms of what phonemes they can pronounce.
I see a distinction between mapping a name more or less faithfully to the sounds and spelling of a language and coming up with a completely different name. For example Brazil in English is not the same as Brasil but is fairly close and fits the language. Whereas IDK where Germany came from.
I'm not a fan of this modern idea that you should get to dictate how others refer to you. E.g. I don't think it makes sense to refer to China as Middle Country for anyone not from China.
