Don't know what type of email he had received. Personally I think it's pretty OK for HR to contract me, but not by sending automatic/template emails.

Notice he said "(they) used the GitHub API to pull my email address", and GitHub API can be used to massively fetch these kind of information for automatic spamming.

Imagine one day you wake up in the morning by few dozens of automatic recruit emails inviting you for a job which don't fit your profile even a bit, will you be happy? This happened to me few times and I'm not very happy about it.

I agreed GitHub shouldn't take the blame because you can hide your email in the account setting, but I don't think he shouldn't be pissed off by the company who was spamming him.
