Thanks for the perspective. I haven't played Error 143, and I wasn't aware that the creator was being hated on because of it. Had I known, I would have tempered my language a bit and made it clear that I'm merely questioning this one particular writing choice in this one particular game, not making assumptions about the creator's character. Ultimately, though, I think many people, including those who probably don't have a strong opinion about the creator either way, feel the same way about the "true" ending.
You made a really good point about how the creator incorporated this into the narrative itself. I know some fanfic writers release bonus chapters if they received enough likes/comments/whatever, which still seems somewhat unnecessary to me, but I agree that I (and probably most) won't have a major problem with it. Ultimately, it's about whether the narrative is complete and is not being held hostage for reasons outside the story itself.
Just piggybacking on your comment a little more: I hope the creator doesn't take these comments personally and can eventually reach a place where they no longer feel the need to do such things in their own passion project. The game is truly one of the best in terms of art, music, and voice acting, all of which are still directed by the creator. Exploring themes that are relevant to a creator's experience often results in profound and moving work. I'd still be willing to check out the creator's future works once they've reached a better headspace.
