My 2 cents are that the issue is promotion not AI

From the rules:

F/LOSS Exception: If your post is about a project that is completely open source & can be self-hosted in full without payment, your post is exempt from the 10% requirement. The exception does not exempt you from the account age requirement.

I would propose making this the requirement and not an exception, forbid all promotion of closed source, and allow the 10% requirement for open source projects.
