The Python chardet library has been relicensed from LGPL to MIT using AI-assisted code rewriting, sparking legal controversy over whether this violates open source licensing principles. The maintainers used Claude Code to rewrite the entire codebase, but critics argue this bypasses traditional 'clean room' rewrite requirements since the AI was exposed to the original LGPL code. This case raises important questions about how AI tools interact with software licensing and what constitutes derivative work in the age of AI code generation.
Background
Open source relicensing traditionally requires unanimous consent from all contributors, which is often impossible for legacy projects. The 'clean room' approach has been the standard method for legally rewriting proprietary or restrictively licensed code.
