Unlike in most RMS-derailed conversations, this time it sounds like it might've confused the grave allegation in the original conversation, at the same time it compounded outrage.
I'm glad RMS now understands that his ideas around this were mistaken, but I think most people aren't wired quite like he is. He might be thinking some kind of "Oh, it turned out that theory seems incorrect, thank you for correcting me with this information I did not have before". But a lot of people were/are upset, and going to respond in various different ways.
I think RMS's intentions remain principled, and I hope RMS now has advisors to help him function best towards those intentions, including helping him understand how different people will perceive and think about things.
