Here's a counter. You're ascribing intent to one's writing, and unless you have a special relationship with Mr. Stallman - you don't know anything.
Because of a radical, illiberal mob, Stallman's life's work has been taken from him.
Few years ago I had had a Junior engineer on my team begin telling me how he finds certain speech so intolerable that he feels he has the right to assault someone for saying it. This is the reasoning behind these kinds of mob justices.
So now I see a mob hurting yet another life, not because of real-world conduct, but because of speech. I see real-world destruction wrought because of speech.
What never occurred to this young man was that there exist people who find the suppression of speech to be what is truly intolerable in this world. That this form of group-think is truly destructive, that actions are of consequence, not speech.
Do pray the pendulum never swings in your direction.
