I guess my real question is why the double y for the way the name is done.
It allows Zelensky to signal his astronomical arrogance clearly, ... AFP willingly cooperates and Sam Barron let's them get away with it.
The Ukrainian leader’s actual last name is Зеленський.
You see the problem here. There is no single established way to transliterate that name into the Latin alphabet. Older Freepers may remember that the same issue arose with the Arabic-language name of the nutjob who ran Libya: Qaddhafi, Gadaffi, etc. See https://www.straightdope.com/21341687/how-are-you-supposed-to-spell-muammar-gaddafi-khadafy-qadhafi
As for the guy in Ukraine, he uses Zelenskyy for his passport and government documents. In the media, you will also see Zelensky, Zelenskyi, and Zelenskiy. I say let him spell his name however he wants.
