The Epstein stuff was more of a last straw. RMS has had terrible reputation for decades, you just don't hear about it unless you talk to people at MIT. The me too movement has shifted the window in such a way that it's finally coming out in a public way.

The FSF sadly functions as a cult of personality for RMS at this point. I do not believe either of them are doing anything to help the cause of FOSS at this point.
