Watermarking is for fools. Those doing the generation and watermarking will control what is perceived as false or true. Watermarks have historically been about proof of ownership or origin. Watermarking fake creations works in reverse, all of a sudden what's void of watermarking is true, but those that control the watermarking can either add them to truths to turn them into fakes or skip watermarking for certain people or organizations, making their fake creations become truths.
