Richard Stallman founded the FSF in 1985. He was the acting president until about 18 months ago when he resigned over comments he made regarding Jeffrey Epstein and his alleged victims. While Stallman is now re-joining the board, he is not serving as president. Geoffrey Knauth holds that position.
The FSF has not provided a comment about Stallman’s return or the role he will play in the foundation at the time of this writing.
