(a) your implication that Stallman is flip-flopping due to public pressure
(b) Stallman's lifetime as a Diogenean polemic who has been shown to stand by his beliefs, no matter how unpopular?
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.
