Well, Berezhnaya put her daughter in Smirnov's (aka Moskvina's ) group. I don't recall any reports of bulling/beating/mistreating the girls in her group, frankly.
As for Davis/Smolkin - they were (ok, he was, she is mainly mute in the interviews) among the only skaters who openly spoke against the war. As far as I understand Smolkin can't go back to Russia at all right now (Davis, of course, can). So am not sure I have much of a problem with their switch (except for feeling sorry for Kazakova/Reviya - somehow I doubt Davis/Smolkin will make it to top 10 at the Worlds without the Russian judging help).
