Every time you buy a key to its case in the game, part of the cost goes to the authors represented in the skins case, in particular russian ones. It is logical that when they are in russia, they pay taxes there. These funds, in due course, go to the manufacture or purchase of ammunition and equipment, which russia needs to fight against us, ukrainians.

Advice for those who, despite the risks and warnings, still want to get skin:
You can buy skins from the market or third-party sites. When it comes to opening keys, open only those where no russian authors were found (but if not found, it does not mean that they are not there) or buy a key, but not in the middle of the game.
