I think the loss of freedoms Richard Stallman described were very much what was already happening around in with the Lisp environment. He was correct in saying this would be repeated as software ate the world.
So roughly the things he was right about were very hard to prevent. Which is partly why he was right.
Stallman came up in the time of mainframes and dumb terminals; so he had mainframe concerns and mainframe critiques.
His relevance now is because we too have shifted to mainframes, but we don't call it mainframe and dumb terminals anymore, we say 'cloud' and 'mobile'. We are rebuilding the future in effigy of our past because it's what we know. Stallman's critiques being relevant again are a testament to the cyclical nature of humanity, like bellbottoms, hightop fades, and vinyl records.
Now if you don't mind, I must iron these JNCO's, times-a-wasting!
I'm not very familiar with the Lisp environment but what Stallman always argued was the logical conclusion of the current (at the time state) of software freedom and redistribution. Nothing being codified was ripe for abuse and misuse, but because the general community consisted of altruistic "doo-gooders" that reality always seemed very far away.
