I assume this is what you think addressed it: "Saying no to locked-down hardware, under names like DRM, "trusted computing" and the like, is not unrealistic."?
My problem is that it becomes very difficult to "say no" if you have no viable alternative, and without open _source_ there never would have been.
I agree that the FOSS fundamentalists reach a point with mere applications that they end up uselessly fixated on the wrong problem, but I don't think it has been the wrong problem either from the start or across the board.
