I would say this is a good thing. I wish that nations actually cared about all the "bad people" as they did with Russian oligarchs though. Everyone loves abramovic and how he helped Chelsea to become a great team, but nobody questions the dirty ways he got that money. You may believe that he was a good person, but he was a terrible person all around, the way he became this rich was corruption from top to bottom.
However, we have people like Saudi Arabian princes that kill journalists that recently bought newcastle and already spent 100+ million on transfers and everyone cheers them. So, either ban all the "bad" money, or ban nobody. If sports keep being this selective then it is not going to be good for anyone.
Unfortunately, that's the reality of life and there will always be bias in this humanity.
A lot of these wealthy people got their position in some illegal ways, one way or another.
But who are we to judge about their riches? And now, some of these Russian oligarchs are receiving sanctions.
We don't know to what extent, but in some way, they are being punished also because of what is happening today.
We can't expect fairness in this society. What we can do is just to live our own lives in rightful manner.
