Interesting debate there. A lot of really good points.

I would also mention Mussorgsky's Great Gates of Kiev, as done here by Emerson Lake and Palmer, and both spelled Kiev: https://www.youtube.com/watch?v=bsPkNUmixMs

Personally I think it boils down to the same thing as when we talk about Munich, when everybody who lives there calls it München.
