Oh that game is vile. That is not in dispute. It has incest. I understand the appeal. Same as for the blackmail and non con plot devices. Forbidden fruit and all that. Possible in fiction, but not in reality. In short, pulp smut.
Steam actually did not remove the game. The developers pulled it. I linked to their statement. The game did not violate any of Steams rules for adult games. Otherwise Steam would not have allowed it on the platform in the first place or pulled it after legit allegations. But the allegations were not legit. You need to pay $ 100 to publish on Steam and they do not accept barely started games. They do have a look before allowing something to be published. It might not be a very scrutinizing look for quality, but they do look out for bad apples. It is big news if Steam has to pull a game after publishing.
Your gloating just reveals the issue I mentioned above. The activists picked an easy target. Easy win. Activists happy. What will be their next target? And that they picked this and used fake evidence to rile up their mob indicates to me, that this was not about the game itself, but about other goals. Like binding their followers and getting new ones.
