>I don't see why an AI can't generate IP, even if the AI is being sold. What's not allowed is selling the generated IP.

Where I live Studio Ghibli are known to be active on C2C marketplaces looking for counterfeit goods. If you were to list a home pressed Totoro pillowcase it would be taken down, sometimes proactively by the marketplace. From that perspective I struggle to see much discernable difference given OpenAI are offering a paid service which allows me to create similar items, and one could argue is promoting it too.
