Anthropic's accidental leak of Claude Code source code ignited a heated debate about AI's impact on intellectual property rights. Sigrid Jin, a Canadian student, used AI tools to rewrite the leaked code in another programming language, resharing it online. While thousands of posts were removed by GitHub at Anthropic's request, Jin's version remained accessible. He argued that rewriting the code created a new, uncopyrightable work, challenging traditional notions of software ownership.

The incident highlights growing tensions as AI tools enable near-instant replication of creative works across industries.
