How was linux revolutionary? Unices had been around for years before that, and IIRC even the choice of a monolithic kernel vs a microkernel architecture was seen as a somewhat conservative choice. Culturally, its not like free software hadnt been a movement for a decade already. IMO Linux's place in history was accidental, occuring because of the confluence of a number of external factors and trends. As another poster noted, if it hadn't been Linux, it would have been BSD or something else entirely. (All of which is not to downplay the value and contributions that Linux did make. But lets keep it in perspective.)
