To be fair - the author didn't "start[s] out" with that statement. They started out with seven(ish) paragraphs explaining exactly why the FSF has become irrelevant and how the foundation cannot reach its goals. The author contends that Stallman (and through his leadership, the FSF) ends up repelling the very kind of interconnected community that could sustain the free software movement. Thus, their first suggestion (replace Stallman, and include different kinds of people in future leadership) is directly related to that specific issue. It's actually a rather nicely written piece, and they support their suggestions in the narrative pretty well. Perhaps you skipped ahead (or perhaps you just disagree, which is certainly your right), but they absolutely didn't "start out" with "orthogonal social issues". They made the case for why those issues matter and then connected them to their suggestions.
