As far as I understand, there's plenty of real-world horrible conduct he could have got fired for too, which has gone without consequence.
This isn't a one-time thing where he never did a bad thing in his life and now is suddenly attacked by a mob. He has been an awful person for a long, long time, and now he is suddenly facing actual consequences.
I'm willing to bet if I went through all your tweets, social media, and personal email, I could find SOMETHING that could have gotten you fired if it ever came to public attention. In fact, I'm sure that's true for just about anybody.
RMS is an "awful person"? I would say that, he's a hero to a lot of people, including me. He might be "social unskilled", but an AWFUL person? I would say that is untrue in any common sense way.
Yes, actively awful. Hostile-working-environment awful. Women cultivating plants in their offices because they know he hates plants and won't creep on them awful.
