As you may know, although Ukraine won the Eurovision last year, it will take place in The United Kingdom due to the war circumstances. A lot of Ukrainian artists were invited to this show, including two of three Ukrainian winners. You're right, the uninvited winner is Ruslana. Nobody knows why. This has been a big disappointment.
This caused unbelievable strong response among Ruslana's fans and outside their community, too! Many posted their statements on social medias and addressed the Eurovision staff to explain their discriminating decision. Ruslana Energy, the fan-powered project, would also like to express support to these people and towards the world of equality where some Eurovision winners from certain country are not favored by the Eurovision among others.
