"This person" is Thomas Bushnell. https://en.wikipedia.org/wiki/Thomas_Bushnell
> who is so eagerly ventilating his opinions to feed the wolves? To me it sounds more like he's upset
This is just my reading, but "A reflection on the departure of RMS" does not have the tone of someone who is upset nor someone who is eager. It has the tone of someone who feels like they have a unique perspective that ought to be shared on a difficult subject.
From the Wikipedia link shared:
"Bushnell was Hurd's official maintainer from its instigation until November 2003, when he posted to the GNU project's discussion mailing list saying that he had been dismissed by Stallman for criticizing the GNU Free Documentation License.[5] Stallman said the dismissal was because Bushnell had been inactive since 2001 and wasn't responding to mail."
Stallman is currently a topic of public interest, so it's unsurprising that people are commenting on his situation, just like you're doing here.
Plenty of people who know Stallman have made it clear that Stallman's behavior is consistent, harmful, and willful. E.g.: https://twitter.com/mjg59/status/1172422966904160257
