Valve really needs to get around to moderating their platform in general. Actively enabling Russian propaganda is really just the tip of the iceberg here.
Much easier for valve to ban the Russian one that most certainly wasn't going to make any money for valve than the money printer that is COD. And it has the perk of never letting then reflect on their own past as part of the war propaganda engine
Its an interesting topic. On one hand fuck russia and this of course needs to be removed - but if something like this is against the rules, why do we let the US army propaganda on steam? Chances of removing that are 0 and if there were a law against it, people would throw fits over it
