This AI Tool Rips Off Open Source Software Without Violating Copyright

The real provocation here isn't that Malus exists as a satirical project — it's that the technique it demonstrates is already available to any developer with access to a capable coding AI. Clean-room reverse engineering has a long legal history (it's how early PC BIOS clones were built), but AI collapses the time and skill cost that previously made it impractical at scale.

MIT Technology Review's piece from April 14 on a potential third major shift in software engineering flagged AI's role in development practices without naming this specific pressure point. Malus makes the tension concrete: if AI agents can reconstruct functionally identical software without touching the original source, the attribution norms that open-source licensing depends on become difficult to enforce, not legally void but practically unverifiable. The expanded Codex capabilities covered across TechCrunch and The Verge around April 16 show exactly the kind of agentic coding tools that could execute this pattern at production scale, not just as a proof of concept.

Watch whether any major open-source foundations, particularly the Linux Foundation or OSI, issue formal guidance on AI-assisted clean-room cloning within the next six months. A policy statement would signal the community is treating this as a structural threat rather than an edge case.
