@liilliil @midgephoto no, it's not the same name. Just as "Kiev" is not the same name as "Kyiv".
If a person tells you they prefer to be referred to in a particular way, instead of the way you referred to them before, you apologize and comply.
Same with a polity that tells you that they prefer to use their own spelling of their capital city, rather than that of their invader and colonizer.
But that, of course, requires some minimal amount of respect towards the person – or the polity.
