The Developer is Russian, it is idiotic to think that they wouldn't store their own money in their own country, just because there's a war started by their president.
If you really cared about morality and war economy, a clear deterrent for you, then the American and European game industry wouldn't exist anymore in your eyes due to their larger lists of war crimes and stained hand, or you'd be a hypocrite.
So just enjoy the game, and play it. It's amazing.
