Free and Open Source Software (FOSS) has been victorious, but the movement from which it stems appears to be a shambles. Many FOSS infrastructure contributors and maintainers are disillusioned, but critical technologists are also finding new ways to bring their work with digital technology into alignment with the political aim of defending the public interest. Understanding how they do so is important if we want to understand how digital infrastructure in the public interest can be made, maintained, and defended in the future.
