There is a second point of view: imagine a Ukrainian living in a Western European country. They moved there because Russian missiles and bombs were falling on their heads and killing their family. They regularly send money to their country to defend against the agressor.

Their neighbor holds a Russian passport. He works at an IT company and earns a nice salary. It's a good life. He complains about being discriminated against. He "doesn't support the aggression". This "not supporting" does not take any material form, he doesn't send money anywhere nor perform any other actions. In the past, he has done absolutely jack squat about the rise of Putin to power (back when doing something was still possible), because he "is apolitical". When the war ends and things blow over, the neighbor will use his Russian passport to go back to Russia, live a good life there using money earned while abroad, and participate in rebuilding the economy, until the next Putin appears on the horizon. He will do absolutely jack squat about the next Putin, because he "is apolitical".

As you can see, it's all upside for the Russian neighbor.

I don't know about others, but something irks me about this common scenario. Sure, there are many subtleties and many ways in which life is complicated. But I see this scenario play out regularly and I can't help thinking that there should be some accountability for the passport you hold.
