A minor controversy over the Touhou 20 demo containing generative AI background textures has been making the rounds on ~~the weeaboo parts of~~ social media: https://www.reddit.com/r/touhou/comments/1kf4h6e/touhou_20_spellcard_backgrounds_might_be/

I have made it my whole life without really figuring out what Touhou is all about, but it seems like at least the English fandom isn't really a fan of generative AI. A lot of them disappointed (or hoping it was an accident due to using stock art websites). Touhou 19 had an arguably anti-AI afterword.

Update: I already owned Touhou 10 so started playing it now that I was thinking of it and stages 3 and 4 are wrecking me send help.
