Yeah Hacker Factor's multi-post critiques are where I first saw it analyzed. For reference they run the popular fotoforensics.com image analysis site.

They also have scathing critique (eg [1]) about the Adobe-led C2PA digital provenance signing, having themselves been part of various groups that seek solutions to the provenance problem.
