Stallman is *ahem* neurodivergent, or in layman's terms, he's a spastic nerdlinger.  Maybe on the spectrum, who knows.  This manifests is several ways.

He's really into software, and he's always been a stubborn grump about freedom (as in *libre*, not as in *gratis*) in the world of computers and information technology.  He, and others, steadfastly pushed back commercial interests in the space and built the gnu ecosystem that we now enjoy as Linux, etc.

He's kind of a hermit, only working on aged computers that still have open source firmware, etc.  And he has never been what you might call... cleaned up?  Bushy beard, wrinkled clothes, etc.  He is the epitome of the 80's hacker stereotype.  (today's neckbeards and incels)

And he is also perfectly willing to say shit that normal people know better than to say out loud.  If something is bad because of a normal person's emotional reaction to it, then he might not know it.  He would only focus on the rational reasons for something.  There are a lot of people like this, and they often end up like him.  Very technically inclined, but also very lonely.

He's no saint, but I would recommend you don't go solely by three single-line quotes out of the many thousands of public writings he has on the record.
