What motivates Apache , Linux to publish open source software?

Daniel Pink in his book Drive takes up this very interesting topic and explores the reason as to what inspires the open source fraternity to keep doing their work without expecting any monetary rewards.

Aside from Apache , Linux even Wikipedia these are the ones who are perfect examples of “intrinsic motivation” in the modern era.These are ones who are not motivated by rewards or monetary and are driven by their sense of autonomy , mastery and motivated by an overarching purpose to do something bigger than themselves.
