I've no idea what Swartz said on the subject and I'm not sure if this implication is intended by you but I would not characterize rms as just being uninformed. There's lots of evidence in this piece that he encountered information and testimonials from abused parties and nevertheless landed at the conclusions he did. I don't know if he holds CSAM or not but I do know he is long past the benefit of the doubt when it comes to his words.
