Funny story, nowhere in that article does it say that the Russian government stepped in and said "This game is banned". The distributor just stopped carrying it because they got enough complaints about it from their customers. If I was a retail store, and was told by several thousand people that the rotting bananas I was selling were making me look bad, I'd stop selling them too, you know?
the game got recently banned in Russia for not glorifying the Red Army
Small correction there, mate. The game was not pulled from shelves for "not glorifying the Red Army". The game was pulled because enough Russians (and probably others too, considering the game was pulled in CIS, not Russia specifically), decided that it was unacceptable. That it was an ignorant, political, crass, and offensive attempt to cater to the West's audience without asking questions at best, and a russophobic, Cold War style, propaganda driven attempt to re-write their own history at worst.
I entirely sympathize with them, the line has to be drawn somewhere. And evidently they have decided that enough is enough, good for them.
