So Valve decided Chaos;Head was too spicy for Steam and refused to allow it without some changes the creators say will have a negative impact on the story.

Meanwhile, Nintendo is allowing it on the Switch with no changes.

So a petition has been set up to ask Valve to reconsider:

I have worries that Valve has been infiltrated by a woke employee or two.
