> I don't know anything about FB's infrastructure

This explains a lot of the comments here. Facebook’s scale is not like anything most engineers have worked on. Facebook probably has logs in the 100s of terabytes. Ensuring that sensitive data isn’t logged takes more than some occasional greps.

What that quote is saying is that the logs that contained the passwords were accessed by 2,000 engineers. Most of those engineers would only be looking at data relevant to their job, only a security engineer would be in a position to notice the passwords, which is what happened.

People scoff at companies that store passwords in plain text on purpose. Inadvertently logging them is not the same thing. And Facebook’s scale is why it’s understandable how it could happen.
