I also wrote this same program for my work as an product manager working on oss projects, but ultimately decided not to release it publicly due to my own ethical concerns. I use it exclusively to contact folks who "touch" my projects repos, in order to get better feedback on the problems they're encountering, and better understand their use cases. But, I also understood this tool would be very valuable to spammers and generally make the quality of life on GitHub worse. I'm also of the opinion that grabbing people's email through the commit history is at least shady if not outright unethical, even if it's public. Most folks I talk to don't realize that their email is public this way. I tried recently to productize my version of this tool [1], with the caveat that you can only use to contact folks that tough repos you or your organization owns. It hasn't seen much success so far though. [1] https://gitologie.com/ https://gitologie.com/
