I don’t have the time to google citable sources to refute false claims without any evidence in the first place. My sources are my own multiple very recent visits to Ukraine(last visit earlier this year), and my extended Ukrainian family and friends who were all taught either only Russian(older and grew up in Russian occupied territories or Eastern Ukraine) and at times spoke Ukrainian under threat of death. Or were taught both Russian and Ukrainian(younger, recent grads from the Kyiv region)
The two articles you linked to show that Ukraine set a minimum 30% quota for songs to be played in Ukrainian, and that people should be greeted in Ukrainian by default and switch languages if asked. Neither of which backs up your outrageous claims.
