As far as I know, Plushenko and Tarasenko's athletes haven't participated in the war, but have competed in Russian competitions and may have -- I haven't been following this -- participated in pro-war shows.
You have Mishin's godson, Memola, who has dual citizenship, and who has been given a pass for getting additional training in Russia. Kvitelashvilli has been treated more like Memola from what I've seen, continuing to train with his Russian coaches, and he's an adult. Same with Gubanova. I haven't seen complaints about skaters who've teamed with Russian skaters to represent their birth countries or the countries that were willing to give them passports to have competitors, like Hektor Giotopoulos-Moore for partnering with Golubeva or Gamez for partnering with Kolovin.
The only skater who's been pressed is Grassl, who has only professional/coaching ties to Russia, and that has petered out, and the only public internal complaints I've seen about any of the countries who've embraced Russian skaters have been from Hungary, and that's about taking away opportunities from Hungarian-born skaters.

So I don't think they will be explaining support and participation in the war in anything more than a perfunctory way anytime soon, unless they continue to participate in Russian events, and even if they are asked why they continue to train in Russia, if they are young, they can just say they live with their parents.
