I've given a lot of thought to this issue and though I've wanted to give Richard Stallman the benefit of the doubt, I've come to an inescapable conclusion:

The FSF board of directors really stepped in it bringing Stallman back, especially in the clandestine manner that they did. They have squandered the goodwill of the community by promoting a controversial figure known for his toxic opinions and decades of bad behavior to a leadership position. The FSF is at grave risk of losing its funding and its reputation, both of which it needs to carry out its mission.

As such, it is appropriate for Stallman and the entire FSF board to resign. John Sullivan has made the right decision. He will doubtless be followed by others -- and hopefully, if Stallman refuses to resign, he will be ousted by the new board.

All of the leadership in open source does not want Stallman in a leadership role because of the toxic effect he has on the community, in particular driving women -- and more recently, those repulsed by pedophilia -- away. There are times to fight social pressure; this is not one of them.
