Sorry, but you have that exactly backwards. The entire linux community runs on social contacts and interactions. As far as anti-capitalist, you obviously don't seem to know what "open source" means. It doesn't mean "free as in beer" software. It means "free as in speech" software. Once I download, or purchase a software program, I should have the right to modify it to suit my needs better.
Once I purchase a car, I am allowed to modify it in any way I choose. Once I purchase a computer, I can modify it in any way I choose. Once I purchase a house, I can modify it in any way I choose.
Since all of the above examples are exposed to the public, I obviously need community permits, etc in order to do most of the work.
BUT I CAN DO IT, LEGALLY, WITHOUT PERMISSION OF THE SELLER!
The whole business model of "license it, not purchase it" is anti-capitaist, and very much anti-social.
In fact, one of the best illustrations of this I have seen recently was in the old George Lucas film "THX 1138."
In that film, the ubiquitous voice of "big brother" or whomever, constantly exhorted the masses to "consume more." In a couple of scenes Duvall's character purchases stuff at the store on the way home from work, then discards it in the trash can as soon as he gets home.
FWIW, I don't see "the Linux crowd" the way you do AT ALL--in fact, I look at them as far more like Free Republic: Unwilling to bend to the will of the "masters."
For myself, I just can't stand the fact that I have spent so much money over the years on MS products, and they don't work worth a ****.
