Ironically, the name "Kyiv" would also be no less offensive since it is written in Latin characters non native to Ukraine instead of the Ukrainian alphabet, which is a derivative of the Cyrillic alphabet. The official and correct spelling is "Київ"

Totally not. Many newly-installed signs in Kyiv are bilingual, in Ukrainian and in English. We have official rules for transliterating Cyrillic into Latin which the government uses.

Pedantically it would be much less, even none at all, offensive, since nobody will care whether a programming language's name is not written in Cyrillic, since the latin alphabet is the default for such names anyway.

I'm pretty offended that you call my home Великобританія too.

> The official and correct spelling … I think "official" and "correct" are two different things especially in countries where social networks and other internet services are prohibited like Ukraine.

Social networks, as a whole, aren't prohibited in Ukraine. Only a couple russian internet services are blocked as part of sanctions against Russia. Because of the... you know... war.
