There's a difference between "unpopular but everyone knows I'm quirky" and "this might be an existential threat to my ability to keep running the FSF etc.".
1. Stallman already has a lifetime of of examples of somewhat poor leadership within the GNU project, resulting in decisions that have compromised GNU and FSF's trajectory (compared to their potential), so once again, these are not new circumstances
2. How is Stallman doing FSF under threat here?
He resigned from the FSF presidency and board yesterday a few hours after my comment, which should answer that question.
