Someone who uses unfree software because it gives him an edge does not appear to share RMS' goals.

... and thus we see how the perfect is necessarily the enemy of the good then? Nonsense.

Two people can share a relative ranking of goodness for outcome states while differing on the methods to reach the better of such states.

I agree with that. It's not a black and white thing and it is sometimes very difficult to even tell goals and approaches apart because a particular approach to solve a larger problem can become an intermediate goal. Sometimes minor differences regarding the preferred approach become dogma. On the other hand, it's always possible to define goals broadly enough to find common ground with almost everybody but then it becomes meaningless. So I still think Stallman's skepticism is legitimate and doesn't necessarily mean he is ignoring other opinions. But I don't know him personally and I don't share his opinions on freedom.
