Could you be a sorcerer if you're related to the DM?

Well, there's plenty of AI that isn't "corporate" AI, and that is itself open. So the distinction you're drawing isn't going to put all AI on one side and all non-AI on the other side.
Heck, there's plenty of "corporate" RPGs that are near-universal staples of the hobby. D&D is owned by Hasbro, along with a lot of its tools.
That would depend on the wording of the general rule, which would depend on what exactly it's trying to accomplish.
You want to ban any discussion of AI except for negative discussion of AI? Worst of both worlds there.
A general rule against spamming should suffice to deal with that.
You don't think people should be discussing what they do at their RPG tables in a TTRPG community? What do you think the purpose of this community is?
If you want to ban anything that isn't "open source" you're going to hit a lot more than just generative AI. Not to mention that there are open models and open source gen AI tools, so you're not even banning generative AI that way.
The best part is that that particular Big Bad was responsible for my character's origin, so my character became quite the Ouroboros out of that. She was epitome of a self-made person.
Reminds me of this Oglaf strip (NSFW, of course - it's Oglaf).
