He first goes on about how "open source" is not about making the world a better place, but then states that the GPL is all about fairness. Well, that's the point - we want a fair world, where everyone's freedoms are respected.
The fairness he mentions is not about having a fair world, but a tit-for-tat kind of fairness. When talking about a fair world, people usually mean a world where everyone is equal, which is not tit-for-tat fairness.
