I'm more concerned about his influence on the free software community: Stallman thankfully lacks direct influence over legal matters, but he has a direct influence over the community's form and function. Essentially, I believe that he discourages valuable contributions to free software by contributing negatively to the impression of what kind of community a potential contributor would be joining. I can't remember an example offhand, but I've heard of existing contributors dissuaded from continuing because of that, as well.
