[Aside] The word "communism" (and "socialism") seem to ring so evil to the American ear! In the impoverished third world, there's not much of a choice. It's either that or the likes of Pinochet, with very little in the middle. [/Aside]
Ah, You young bucks were nary a glint during the 60's hippie movement--which were part of my formative years..
Back in the 60's we used to do many things that sounded so much like the Open Source movement of today. The preferred word then was "communalism". And quite honestly I don't see a whole lot of difference between "open source" and the commune lifestyle. Just as the movements of the 60's brought global change (even though governments and industry often deny it) so too will the Open Source movement to much of technology. And even if the word "Linux" per se fades from the techno-vernacular 20 years from now, it's soul will live on within many of the companies that deny it now. You can see it already with the likes of the mighty IBM company (and even proprietary Apple) supporting open source. Some day they will make it sound as if it was their idea! Such companies will make their money on hardware. It's the non-hardware companies like Microsoft who will be most hurt by the "movement." Thus Balmer's rhetoric.
You don't see too many communes any more, but their ideals (now phrases like environment, equal rights, etc.) will be a major part of our culture forever.
