I'd add rms/Richard Stallman to that list of famous emacs users. He's famous for way more than just gnu emacs, so it's not quite cheating.

I also wondered why RMS is not in the list of famous people using Emacs. He's the frickin creator and also famous. Or is he a persona non grata now?

I found it kinda funny he's not on the list; he should be the first there, without him Emacs would probably be a footnote in SW history.
