Before the other day when this misinformation campaign began, nobody ever associated the song with groypers. Its always been associated with anti-Fascist, anti-Nazi groups, which contain a completely different set of beliefs. In recent history the only people to ever use the song for political purposes have been left-wing groups: Protestors against the AfD in Germany, communist priest Andrea Gallo, movement against Jair Bolsonaro in Brazil, left-wing protests against Meloni in Italy.
Combining the lack of substantial evidence of association with groypers with the history of the song being used by left-wing movements, in addition to the evidence in my post above and elsewhere, its clear that this cannot be reasonably associated with groypers by any evidence-oriented person.
