I'll be extremely charitable and assume you meant to link to the site in general as a rebuttal, and not specifically to the webpage that just lists his awards, because saying that someone's misdeeds don't matter because they also did great things is a rather gross viewpoint and a continuing insult to the people who are victims both of the "Great Men" and the wannabe-"Great Men" who feel safe doing such acts in the belief that future greatness will similarly exonerate them.
The page that's most responsive to what's brought up is here: https://stallmansupport.org/debunking-false-accusations-agai.... However, I feel that it doesn't really debunk the core accusations here, which is essentially that Stallman's views on what constitutes consent just aren't acceptable in today's world.
