No one really needed media sensationalism to draw a pattern of behavior unbefitting the leadership of the FSF. That some random people overstated some aspects of his Epstein thoughts isn't really why this happened.
It's also a bit ironic you've decided to call it a witch hunt. Witch hunts happened when folks decided to start blaming women for everything without even a veneer of logic or civility. And here we are with a man, having possessed a long history of specific behaviors, being called to account for exactly those behaviors. It's ironic simply because the privileges RMS was exercising are so ingrained in your worldview that demanding he stop treating women like lesser beings is–to you, at least fundamentally irrational and unfair demand.
RMS had hundreds of other controversial opinions. Uttering them did not result in this. In fact, no single act of sexism got him here either. So suggesting that this is merely society punishing a misunderstood outsider on a whim is itself pretty uncalled for.
