It's almost as if many countries within Eastern Europe and Asia have generational trauma associated with acts of violence, oppression, and genocide connected to those symbols.
I've never understood the obsession with Soviet iconography within communist spaces, especially when there are plenty of communists that acknowledge that the Soviet Union never actually lived up to the ideals of communism, and acknowledge the acts of imperialism and genocide committed by their regime.
The swastika and other ancient symbols are banned for similar reasons in many countries for their association with fascists, and most people seem to be on board with it. But when countries that were directly harmed by communist regimes start to ban soviet iconography, there is suddenly a double standard and a lack of understanding.
I think modern communists who sincerely believe in social justice need to divorce themselves from these symbols of oppression. There are plenty of symbols of solidarity, unity, and workers empowerment that could be used that don't have the same level of taint. I'm a fan of the big dipper myself.
