I really am not trying to start a "fire fight" over Objectivism, but it occurs to me the individualist nature of the prototypical "hacker" is consistent with the values of Objectivism - self-reliance, work for one's own rational self-interest, don't "conform", etc.
(Full disclosure: I am a member of the Objectivist Party - http://www.objectivistparty.org)
Both from a personality standpoint of "individualism" and from a more general logical thinking/epistemological standpoint ("A is A") it seems to me that Objectivist values and beliefs are Hacker values and beliefs, or, at least, a "hacker" is statistically more likely than the average person to gravitate towards objectivism.
