(Author of the original article here) It was really pretty naive - nobody would plan for an RTS now without planning a series of patches to do the inevitable adjustments. Even for AOK we planned to patch and adjust. The 'general argument' was a MS publisher stance as quoted by Matt Pritchard - to do a patch in those days through the MS system meant a lengthy and expensive full test process, rollout, creation of a patch system, etc - so it was something you planned and budgeted for. The concept of 'day-one-patch' would have been pretty horrific. Patching is now something you integrate, plan for and expect - because we aren't shipping on gold masters to a printing company.
