Key Points

  • MALUS is a satirical take on 'clean room as a service' that parodies discussions about bypassing open-source licenses with AI-generated code.
  • The piece imagines proprietary AI agents recreating open-source projects with legally distinct code, no attribution, and no copyleft obligations.
  • Willison frames the post as a joke while using the satire to critique the license-washing vibe in the AI/OSS conversation.
  • It references related debates about relicensing open source through clean-room implementations and situates the satire within ongoing licensing tensions.

MALUS - Clean Room as a Service (via) Brutal satire on the whole vibe-porting license washing thing (previously):

Finally, liberation from open source license obligations.

Our proprietary AI robots independently recreate any open source project from scratch. The result? Legally distinct code with corporate-friendly licensing. No attribution. No copyleft. No problems..

I admit it took me a moment to confirm that this was a joke. Just too on-the-nose.
