Id be very careful with this. Russian celebs and sports stars abroad are one of the very few sections that are openly critical of the actions in Ukraine and get huge exposure in Russia due to their social media feeds. Casting them off not only reduces the likelihood of those individuals feeling empowered to do the same, it enforces the anti west resentment.
I get it with the national team, individuals is different though.
I think the argument is that they are representing Russia at these events and thus Russia benefits from it's name being on world stage.
I think they'll all be asked to compete without the flag or face suspension.
