The business model seems to be that Konami is threatening the fanbase that dumb rubes will make stupid decisions about "The Silent Hill Canon" and so that if they want things to not become fucking stupid and bad, they should pay for premium season pass minigames so they can cobble together a coherent narrative.

With the secondary threat that this will matter in future games, despite the fact that the games that Silent Hill fans actually think count do not have a particularly shared "canon."

Edit: My second guess from where this business model came from is some guy at Konami watched the Jerma Dollhouse stream right before a pitch meeting.
