While it was known to not be isolated beforehand, it's pretty clear to me that a number of people have felt safe to tell their own stories in the couple days since this broke. I live near MIT but did not attend, and so I am not in any particularly privileged circles; despite that, this incident prompted a lot of people to speak up about RMS's consistent bad personal behavior as well as his bad public behavior. These sorts of things have a way of providing courage to people who have felt suppressed--someone is brave enough to kick one rock and dozens more come with. I would submit that if a nobody like me is hearing that stuff it is a near-certainty that people with hire-and-fire authority at MIT, and in decision-making roles at the FSF and GNOME, are hearing it and likely more.
This is what makes most of the protestations in this thread (not, I stress, the ones that you're laying out) so disheartening. On one hand you've got people adjusting their pince-nez and going "well, really, don't we need to have a conversation about statutory rape?" (we don't), while you've got another contingent who are all about clapping for pedophiles to "own the libs". It's just...really gross, and it's not about "free thinking" or "free speech" at all. (And it never really is.)
