>>>Altruistic systems don't scale (see communism).

Altruistic systems don't necessarily scale. GNU, Linux, and Apache would like to tell you that it absolutely can scale.

>>I just can't believe that you think that big budget software like say an operating system could be funded through a threshold pledge system and then distributed for free. It seems rather naive

I completely agree with you that it seems naive. I wouldn't believe it myself if I wasn't using it to send you this comment.
