1 -- No one is saying that if you don't have the same views as the majority, you're problematic. But some non-majority views, like the one you link to -- his last-minute recant of his belief that "voluntary pedophilia" was a thing and didn't harm children -- are nevertheless beyond the pale.
2 -- Stop using "because autism" as an excuse. It's an insult to the many people on the spectrum who don't do and say shitty things. Also, has RMS been diagnosed? Are you a psychologist? If not, I don't think you're qualified to make that statement. I'm not sure you're even reading the same thing I am; she specifically calls out incidents and people who claim RMS specifically harassed them. If you look a bit on Twitter, there are more women coming out who have been similarly harassed. I agree that standards change over time, but when the behavior of 40 has remained consistent over the next 40 years, that's a huge problem.
3 -- It is entirely possible that a single piece can be about and triggered by the actions of one person, but then expand to be more general. Not sure why you can't see that.
4 -- So what? I mean... sure, she has flaws, but so do we all, and that has nothing to do why RMS does shitty things. Also, she _posted the verbatim contents of the emails_ (including the most relevant part, right there, a couple paragraphs into her post). It's on Vice (etc.) for not, y'know, actually reading them and reporting things factually.
I'm just not really sure why you feel the need to latch onto this single post so tightly. It was a catalyst, to be sure, and several media outlets did some incredibly irresponsible, dishonest reporting. But that doesn't change the fact that RMS has been engaging in reprehensible behavior for decades. It's feeling like you're looking at a list of 10 bad things and are saying, "wait, everything is ok because one of these things on the list was wrong!" This might be a shitty straw to break the camel's back, but the camel's back was overdue in breaking.
