The world needs someone like Stallman quite simply because his views are so extreme. You need an extremist so that moderates can seem reasonable.
The reality is that what may have seemed a completely out there view can become the new normal within a surprisingly short time when the environment or culture changes. Apart from politics, you see this in everything from fashion to music, business etc. (e.g. predicting the death of print or record shops, or 'did I really think I looked good in that - what the hell was I thinking?')
