> Ezra Zygmuntowitz pointed GitHub in my direction, and let me take the time to really get into the problem with the GitHub team

This sentence is funny to me. Maybe because I'm not a native speaker, but I can't avoid reading it as a big problem with the GH team itself, heh. I was expecting the next sentences to "get into" that.

> I wonder if Luciano hadn’t found it, how long it might have been before it was found

I think perhaps only GH or one of the big cloud providers would have stumbled upon it, few places I can think of that would have thousands and thousands of keys stored from users.
