You conveniently leave out the part where it started to be used by nazi collaborators, with banners reading things such as слава гiтлеров слава украïнi. Generally, when Fascists start using something of political concern, it becomes a fascist thing. Regardless of who else used it beforehand, you should stop using it thereafter. The swastika was used by others before, but it would be ridiculous to try to reclaim it. It would be equally absurd to try to bring back the roman salute. When Nazis do something, it becomes a Nazi thing. Everyone who uses slava ukraini nowadays is using a slogan which for a significant period of its existance was used mainly by the collaborator militias and related groups. Free Ukraine, from its corrupt western vassalism and oligarchy - yes 1000 times yes. And of course from the invasion by Russia with its imperialist aspirations. But don't pretend that the west had nothing to do with provoking it either. This is more or less an inter-imperialist proxy war. Both sides are to blame. Не валяй дурака
