I really have no knowledge of the Stalman situation but just wanted to strongly disagree. Someone's contributions to a given field should not grant them any leeway whatsoever.
All people should be held to the same standards of behaviour regardless of their social standing. Otherwise we end up with powerful people abusing their privilege. That is sadly the reality in today's world and "cancel culture" is the resulting backlash against that inequality.
As with most social corrections there will be people that will argue the pendulum has swung too far but that doesn't change the fact that it needed to swing.
