Those are just reformulation of the same concept which has nothing to do with communism, just with soviet state nostalgia. Plus a few were banned after Russia's invasion for supporting the invaders (and they are related to the soviet nostalgia kind). Anyway they lost almost all support, I was even a bit surprised that any Ukrainian I know, even Russian-speaking pro-Russia-ties people are very anti-Russia now - being invaded feels even more like an betrayal for them. Of course I do not exclude that some Ukrainians genuinely support the Russia's narrative, but among hundreds I know personally there is not a single one.

Banning certain parties is along the same lines as Germany banning Nazi party, or would you suggest that's oppression of freedom as well?

Clearly, I do not enjoy this division with Russia, I have Russian family, friends, colleagues. But what their state did is just not the way to do things, it damaged irreparably relations and any remaining pro-Russian political parties or sentiments in Ukraine for a generation. I rather prefer some balance and discourse would continue but nobody did more to push Ukraine away from any pro-Russian politics (even shaped as soviet nostalgia with "communist" banner) than Russia itself.
