To Keybase people here, I'm not sure why you can or won't open/free the software. However, it might be possible that you meet your goal by using shared source that licenses published source for specific uses as educational/academic, security review, and/or build locally from source. Doesn't allow commercial use or forks of that code. There's precedent for that in security software, like Cryptophone doing it (below) for review. I suggest considering an option like that if open/free source doesn't work since it still increases confidence in Keybase. https://www.cryptophone.de/en/background/source-code/ https://www.cryptophone.de/en/background/source-code/
