> NYT wanted to report on who he was.
They wanted to report specifically his birth/legal name, with no plausible public interest reason. If it wasn't "stochastic terrorism" (as the buzzword of the day was) then it sure looked a lot like it.
> He doxxed himself years before that
Few people manage to keep anything 100% secret. Realistically private/public is a spectrum not a binary, and publication in the NYT is a pretty drastic step up.
