guillaumemeyer/watermarks-remover appeared August 11 and hit 634 stars and 61 forks in 24 hours, targeting provenance marks from Anthropic, Google's SynthID-Text, OpenAI, and Kirchenbauer-style implementations across three layers: invisible Unicode hygiene, statistical token-sampling removal via rewrite hooks, and C2PA manifest/EXIF/XMP stripping across PNG, JPEG, SVG, PDF, DOCX, ODT, HTML, Markdown (GitHub). The README frames it as privacy hygiene and disclaims academic fraud, while conceding it can't certify vendor detectors will fail. Provenance marking is roughly nine months old as a shipping feature and the removal tooling is already trending. That's the whole watermarking debate compressed into one repo.
