Miss Julie Ann Horvath made news. Others claim her story isn’t exhaustive. See link.
Edit: This from her twitter feed: “Any rumor JD accuses me of originating in that post [that a married co-worker’s child’s paternity was illegitimate], to my knowledge, existed long before I even worked at GitHub. How does that work JD?”
So, there was a rumor, and she claims to have not originated the rumor…
Occasionally, the tenor of the denial reveals truth.
