I'm not sure, but I'm guessing it's because of the dismissive tone regarding early proponents. I lived through this period and remember being attracted to Booch notation and similar early efforts (as well as GoF patterns, etc.). Ours is still a relatively young profession and before UML codified some of the ways to view problems clearly (from a particular perspective), one was often reduced to writing out algorithms and data structures and diagramming in off-the-cuff ways.
