Much of what is being said are opinions or interpretation not facts. And because they are controversial, and often connected to trauma,, people don't tend to broadcast them until a "crisis" like the current one encourages sharing stories and makes it safer to do so.
But view the video linked to in child comments to the one you're replying to, and draw your own conclusion about what RMS actually said and the context in which it was said.
My view is that the comment you're replying to describes an incident that grossly mischaracterises what actually occurred. There were problems, and there was an inadvisable sexual joke, and probably some women were probably put off contributing to OSS, and it echoed some aspects of misogyny taking place in the rest of their lives - workplace, home, everywhere.
Consider, at the same event, the person you replied to admits that someone thought what they were saying was problematic too (thus the yanking of the mic from their hand). So, at very least, there were strongly differing views at the time.
I think it's good that people, on occasions of heightened awareness like this, feel able to share their presumably long history of traumatic and unwelcoming experiences, in OSS and in society elsewhere.
The shit women (among others) have had to endure, and still do, continues to be awful, both in OSS and elsewhere.
But it's terrible that the same phenomenon involves people empowering themselves in groups by gathering to destroy other people from more or less the same "side", when the social errors being committed by each person are not that different from each other, and what I'd call the "real criminals" (rapists, abusive partners, abusive bosses etc) are strangely not targetted in the debate.
For a movement that is supposed to be based on high principles of inclusion, empowerment, and social justice, it's tragic to those principles made weak and breaking down, because people don't know how to apply them in situations like this.
