I think the argument, with regards to Jobs, was rather that Stallman was inappropriate on writing his statements so soon after Job's death. Edit: To clarify, the bulk of the arguments where not against his ideas but rather directly concerned with his behavior. I don't consider it character assassination. The counter-argument was that he was correct, which does not actually excuse the way he stated it. You can say something correct in the wrong manner.

Now, regarding the rider for speaking engagement, I would agree that the outright mocking seen there was uncouth.
