My entire life, whther while i was living in Japan, Germany, or the US, the spelling of Kiev and the pronunciation of it has remained constant. I know the locals will have different spellings and pronunciations just like cities and personal names throughout the world, but this has completely changed in the West over thw last few weeks. Now its Kyiv (Keev) vs Kee-ehv.
I know this seems small or trivial, but this is extremely fishy to me.
I have ALWAYS known it as Kiev and literally got confused when I kept seeing Kyiv and decided to go to yandex and search, "when was Kiev changed to Kyiv?" and I saw a VERY interesting post on quora.com. A very interesting response came from a guy a who was born and raised in Kiev. Check out Roman's response to this proposed question!

I feel the same way about concert venues when they rename (alot) I refer to them as the original name
