The way Itch implements AI disclosure is not quite satisfactorial. I think the textual disclosure as seen on Steam to be better. Also, the way these "tags" are shown, or rather not shown makes it feel like a hack. Also, some devs select those tags manually, adding to confusion of players and other devs. Not many people read this thread and understand how this really works. Maybe 5000 users read this thread. Probably less.
Itch currently has a yes or no and that might be ok for assets, but not for games. Customers look for different qualities in games and assets. Being AI free can be a vital quality for assets, so yes/no makes sense.
But players will have other standards for games. If they care for AI, it will be most likey be for the "content". To my understanding of language, content is what is shown, and not the method how it is shown. So, code is not content. It might be in some cases, but not generally. Using state of the art coding technologies and being lumped togher with ai slop creators is not really good for morale of developers. Not answering the AI disclosure might be prudent, but it is not elegant.
