Sometimes people's flaws prevent them and the people they work with from doing good work.
A lot of people I'd describe as "principled" don't want to be anywhere near Stallman for various reasons, often related to their principles. Maybe he's just cleared his orbit of anyone else who actually fits your 4 criteria, so only appears to be unique. This seems like a rather common failure mode of personality cults, tbh.
