Open Source is not a gift. It is a contract.
Google is shutting down Gemini CLI and replacing it with a closed-source tool. 100,000 stars, 6,000 contributions, hundreds of volunteers. Enterprise customers keep access. The community that built it gets 30 days. When the value lives in a proprietary API, even forking cannot save you.
