Not to diss you, but these kind of questions ("Why another distro?", "Why another language?", "Why another ssh server/client/framework"? and so forth) have been asked zillions of times already, and the answer is always the same: the current offerings were not enough, for whatever definition of "enough" was at the time, and those offerings were tied down by whatever social structure or framework that did not work for these creative folks. I love that we have the freedom to explore with technology in the way we do.
I'm kinda on the opposite end of the spectrum. I love this world where 45 people try to race toward the same goal. Sometimes the best ideas win. Sometimes the fastest to the first goal wins. Sometimes everyone gives up. Sometimes we have competing standards we have to sift through. It's a mess, but it's a beautiful mess.
Most people aren't interested in cooperating. The neat thing about collaboration is that work can be shared without cooperation. Free software is inherently anarchist. Sure, there are several successful cooperative organizations, but they all benefit primarily from the collaboration they do with everyone else, and vice versa.
Variety and change is basically the definition of life itself. Uniformity and stasis are pretty good definitions of death.
Kooky offshoots and dead-ends are not waste, they are the very definition of life.
Imagine a world without life? Sure, absoulutely do imagine that, so that you can understand how and why you would never want that and should never suggest it, and know exactly how to respond to anyone who comes along and tries to float this genius idea of efficiency.
