Four key themes that dominate the discussion
| # | Theme | Representative quotes |
|---|---|---|
| 1 | Clean‑room vs. derivative work | “People do cleanroom implementations as a precaution against a lawsuit, but it’s not a necessary element.” – Pannoniae |
| 2 | Burden of proof in copyright claims | “The burden of proof is on the accuser.” – Ukv |
| 3 | Copyrightability of AI‑generated code | “All AI generated code is tainted with GPL/LGPL because the LLMs might have been taught with it.” – p0w3n3d |
| 4 | Licensing implications of a rewrite | “Licensed code, when modified, must be released under the same LGPL license.” – mytailorisrich |
These four threads capture the core of the debate: whether an AI‑driven rewrite can be considered a clean‑room implementation, who must prove copying, whether AI output can be copyrighted, and how the LGPL’s requirements affect the new project’s license.
