Well, if you know which users are part of this GitHub organisation (their public member list is empty, ironically), you might be able to grab their real emails from their Git commits. What you do with them I'll leave up to your imagination... The specific user who responded with "we thought long about this update and ultimately as it stands today it is not a change we would like to add" uses their @users.noreply.github.com email for Git, but their employer and hometown are public on their profile, and a quick search gives you the mail address. While I live nearby, I don't intend on paying them a visit, plus it seems to be a shared office highrise, but I might just write them a strongly-worded letter.
