This reminds me of similar questions around both Atomic Heart and Hogwarts: Legacy, and I think there are a couple differences in both cases.

In the case of Atomic Heart, part of the controversy was related to the sexualized robots that bear a traditional Ukranian hairstyle, and how subservient they are towards the player, as well as the way the USSR was depicted in general in the game. Taken together, a lot of people saw that as reflective of the current and common attitude of Ukraine being a subject state of Russia. So the monetary support for the devs were potentially directly benefiting people with questionable views.

In the case of Hogwarts: Legacy, the connection to a bad actor is even more clear cut, wrt JKR. Abstaining from purchasing it was roundly discussed as a boycott of her and her views, even if she had minimal connection to the game itself (we know she did financially benefit from it, as she stated it herself on Xitter).

I think this is one too many steps removed for me to condemn it in the same vein. Yes, Russia will benefit in tax revenue from it, but the studio isn't state-owned or something; it's no different than buying something made (in whole or part) in China giving tax money to the CCP to further Uighur genocide in Xinjiang, or tax money in the US going towards genocide in Gaza via military aid.

I'm not saying you're a hypocrite if you choose to not buy this but still pay US taxes, because ultimately the consequences that you face for those 2 actions is very different. I might say it's hypocritical to buy Chinese goods though, given they are still trading with Russia and supplying them materials.

Personally, I'm not going to treat all people as proxies for their government; that's too close to collective punishment.
