Russia Ukraine war, page-227602

....the answer is obvious .....or should be !
Ukraine was dominated by russia for ages .....russian language ws encouraged and official and is widely spoken ....Davydov , Zelensky both russian speakers as first language so not surprising the odd time pre-war there was some use of Kiev

.....but now .....people in Ukraine understandablt tried to avoid anything russian , try to more correct with naming
"Kyiv" on maps
"Kyiv Post "
"Hilton Kyiv' etc

the few that do spell Kiev - on HC or in Ukraine -do so as a means of support for russia

....but you dodged the thrust of my post calling out the perjorative use of the term REGIME for Zelenskys governemnt
