If Facebook already embeds user IDs in images (AI or no AI) I can only drool to think what kind tracking, advertising and mass surveillance opportunities are coming.
I don't see anything about watermarking in the linked article, it's about labelling requirements. It describes situations where you are required to disclose if an image was AI-generated.
