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.

#6This is a great statistical analysis and it was a pleasure to read, but I wasn't expecting the claims to be so poorly supported.
There's also a reply from one of the Meta authors there, worth checking out.

#7A watermark is not just “transparency.” It can reveal what tool someone used, how they work, or that an image came from a stigmatized platform. In sensitive contexts—politics, sexuality, medical issues, protest material, or private expression—that can become surveillance.
I am working on Saigon Watermarks: https://apps.apple.com/us/app/saigon-watermark/id6777061197 for detecting and removing provenence markers in AI.
The tool also removes c2pa markers, which google is now linking the device that took the photo with the photo.
scary stuff.

The actual rules don't say that I think, it's more about the intention that the watermark is embedded with the image/multimedia itself, so it's persisting even if someone "right-click > save" the image or takes a screenshot, not literally regulated the watermark has to be unremovable.
> (Summary) The icon should be directly embedded into the deep fake or published text (except for creative works), unless equivalent alternatives are available such as a user interface overlay. The icon must be visible when content is reshared or downloaded.
