Anthropic Issues DMCA Takedown for Claude Code Reverse-Engineering Attempt

Anthropic has issued DMCA takedown notices to a developer who attempted to reverse-engineer and release the source code for its AI coding tool, Claude Code. This contrasts with OpenAI's approach to its competing Codex CLI tool, which is available under an Apache 2.0 license that allows for distribution and modification, gaining OpenAI goodwill among developers who have contributed dozens of improvements.
