Track Record

On November 3, 2022 developer-attorney Matthew Butterick filed a proposed class action against GitHub, Microsoft and OpenAI alleging that GitHub Copilot reproduces verbatim or near-verbatim snippets of open-source code without preserving the original license, author attribution, or copyright notices required by permissive licenses such as MIT, Apache and GPL. The Northern District of California allowed two contract-related claims to proceed in 2024 while dismissing some DMCA claims. The case remains a flagship test of fair-use limits in code-trained generative AI.

In October 2019 more than 200 GitHub employees signed an open letter calling on the company to terminate its $200,000 contract with US Immigration and Customs Enforcement (ICE). At least five engineers publicly resigned in protest. CEO Nat Friedman defended the contract by saying GitHub products were 'general-purpose developer tools' and the company would not cancel the contract, while pledging $500,000 in donations to immigrant-rights organizations. The contract has been renewed each year since.
