As a recipient of that email (several times), it's apparent a script went bad that had all users on the To: line, though still iterating through each company account. IMO it looks like a pretty basic coding error ... something that should have been checked before sending of course. No real account info aside from email addrs and company name was exposed.

Github did follow up with a "sorry" email. Note that it wasn't all true enterprise users. I did trial enterprise, but my company stayed with the hosted version only. Also, lots of the names on there were evidently @github test users and others I recognized as tire kickers (knowing they use only hosted GH as well).

End result - a little egg on face for Github, one very sad day for script kiddie email coder, and an indication (if complete) that Github has << 3000 GH Enterprise users.
