If I am honest, I did not understand your point, then. Your start-off was that the GPL segments between users and developers and disagreeing with that.
What I tried to offer as a counterpoint, is that the GPL does not actually segment between the two, it just mandates that this non-segmentation be conferred at every new iteration of distribution.
What you call "permissive" then is only permissive in the short term, because it precisely introduces this segmentation between users and developers in the long term. If you look at this as a tree structure, it's permissive only to your immediate children, because you are granting them the right to take away this precise freedom from your grandchildren, thus introducing the separation between users and developers.
Or in GNU speak: you are allowing your user/developes to take away their users's freedom 1 and 3, so since there are four freedoms, I will claim that this is at least half the point of the GPL.
