@NotVerySmart, Lewin’s work is not wiped off the internet completely. You may very well be able to find his lectures elsewhere. You just will no longer find them on edX which is the delivery vehicle for MIT’s MOOC’s. Once they were put on notice of his transgressions, they really had no other choice but to revoke his use of the site. How could they ethically or legally allow him to use an Institute sponsored site to harass students? My D attends MIT and the consensus among her friends, both male and female, is that MIT stepped up and did the right thing.
As far as Feynman is concerned, his legacy is secure. Neither my opinion nor anyone else’s is going to change that. But I will say that there are few women I know that could read the chapter “You Just Ask Them?” in his book “Surely You’re Joking” and come away with any respect for the man.
