>It enrages general public and unites against the west

Oh, you're right... the world is currently in a very complicated situation. While banning russian competitors enrages some of the general public (and spreading the "west is russophobic" propaganda), allowing russian competitors means Putin can take profit from these competitions as well

Wonder what can be done in this case, it's really complicated...

Indeed! Any participation of Russia in competitions has been used by Putin to push their propaganda further.

Also, as far as i know, participation of russians in big competitions, sports or not, is very profitable for Russia as well (so it ends up profiting more violence in Ukraine)
