This feels like nothing more than linkbait with no value-add. Emails are public on Github anyways, so simply browsing to github.com/<username> will show the users registered address. I guess it's almost interesting that it can be done programmatically, but I never suspected anything less.

Not everyone includes their email in their GitHub profile. For instance, the creator of this tool’s profile at https://github.com/hodgesmr does not include his email address.

This tool does not rely on email addresses being in profiles. It can look up the email addresses used in commits in the user’s repos, and use heuristics to choose the most likely one.

Thanks for the clarification
