Before Epstein was known to be evil, Minsky accepted support from Epstein for science, and also had a sexual encounter with a girl who was ostensibly a masseuse in Epstein's employ but was actually being forced by Epstein to have sex with his guests--it is not clear which of those guests, if any, knew that she was being forced to do more than just give them massages.
It is this sexual encounter that Stallman was defending, and that the poster I was replying to compared to people defending Ito's dealings with Epstein.
After Epstein was known to be evil, both Minsky and Ito did accept support from him. Minsky, as far as I can tell, did so publicly with no attempt to hide it, and I haven't seen any suggestions that he continued to do so after MIT decided to stop accepting donations from Epstein. Ito, on the other hand, appears to have continued to do so, and appears to have tried to keep it secret.
