The proposed legislation threatens the legal foundation of open-source software by mandating license revocation. This creates massive uncertainty for developers and organizations relying on shared AI models and code, potentially disrupting the entire software supply chain.
GitHub has joined an open source coalition of Black Forest Labs, Hugging Face, and Mozilla Corporation calling for targeted amendments to California’s AI Transparency Act (SB 942, as proposed to be amended in SB 1000). Read the full letter here.
At issue is a narrow but important problem for developers: as currently drafted, the bill’s license revocation provisions conflict with how open source licenses work in practice. Open source licenses are designed to be perpetual and irrevocable, which is what allows developers to reliably build on, reuse, and share code across projects and organizations.
The proposed language would require developers to revoke licenses if downstream users fail to meet certain obligations. That approach is incompatible with widely used open source licenses, and it could introduce uncertainty across the software supply chain—particularly for collaborative and community-driven projects.
The coalition’s letter explains that this requirement is not necessary to achieve the bill’s goals. Developers who modify and deploy AI systems are already directly covered by the law, and enforcement mechanisms remain in place. At the same time, there is a workable alternative: aligning with the EU’s approach in the AI Act Transparency Code of Practice, which recognizes the distinct nature of the open source ecosystem and acknowledges that notifying downstream users of best practices in documentation is sufficient.
GitHub supports these amendments because they preserve the bill’s transparency objectives while maintaining compatibility with open source development. Getting this balance right is critical to ensuring that California continues to support both AI accountability and open, collaborative innovation.
Call to action
We encourage you to review the letter and share your perspective with policymakers. Clear, technically grounded feedback that includes open source developers and civil society can help ensure that AI transparency requirements work in practice without compromising the open source ecosystem that underpins AI innovation.

This app shifts AI from a simple chat interface to a comprehensive workspace. By integrating context-aware agents, interactive UI previews, and automated PR management, it streamlines the entire development lifecycle from initial coding to final merge.
Understanding the trade-off between pre-built AI harnesses and raw API access helps engineers optimize for development speed versus custom control. It clarifies how to manage LLM costs and token efficiency while leveraging existing SDLC integrations.
AI has flipped the economics of development. By using agents to prototype small requests, teams can replace speculative meetings with evidence-based reviews. This shifts the engineer's role from code producer to an evaluator of risk, focusing on what is truly expensive to maintain.
