Hmm, on second thought, you may be right and I probably overreacted. I still don't really believe Putin would exact revenge on Volozh — Oleg Tinkoff defected back in spring 2022, and I think his family is quite fine — but relying on Russia not being stupid doesn't sound wise right now.
There's probably no hard proof, but Russia is allegedly funding far-right movements like AfD and whatever Le Pen's party in France is now called. Also, see the career of Gerhard Schroeder, first German chancellor and then a top Gazprom official.
