Let's not pretend that people are even mad at him for anything he did. It's just journalists contorting facts to make a good story, and Silicon Valley's inability to discern truth.
If he'd ever showed any sign that he wanted to improve people might be a bit more tolerant. He's had years to put support in place, and he's declined to do so. He keeps blaming lack of understanding on other people - [I'm sorry you misunderstood what I said, vs I'm sorry I said what I said].
And now we have dozens of people who describe the harassment and aggression they faced when working with him.
People defending RMS on HN want it both ways: when allegations are made these people will say "it's unfair to put this in public; complaints need to be dealt with in private". But then when we're trying to talk about RMS's behaviours those same people will ask for huge amounts of detail in order to litigate the accusations.
It's an inconsistent approach that's driven by defending RMS rather than wanting to find out what the truth is.
