He's never adequately explained from what I can tell why he made those statements in the first place. If he could provide that additional insight, I think it would help others evaluate the sincerity of his apology.
The question that I have for Mr. Stallman is a very frank one: were his remarks in support of pedophilia designed to persuade Mr. Epstein to donate part of his $500 million estate to the Free Software Foundation, much like he observed role-models such as MIT president Rafael Reif do for Mr. Epstein when Dr. Reif sent Mr. Epstein a personally signed thank-you note for his donation to the Media Lab, or colleagues like Martin Nowak do for Mr. Epstein when Dr. Nowak created a web page on a university website and an office in his department for a convicted child-rapist in exchange for millions in donations to his academic program at Harvard.
