Switched offers an overview of the 10 most stubborn people in tech. One of them is Linus Torvalds:
Fact: Most of us will never be able to write a code for a computer operating system. If we did, chances are we wouldn't give it away for free either, but that's exactly what Linus Torvalds did when he created Linux. The software for the operating system is free to use and anyone can modify and distribute it, although Torvalds has still made some dough from it. In a 2007 interview, he said he doesn't mind missing out on all the money he could've made, saying "I have a very good life, doing something that I think is really interesting, and something that I think actually matters for people, not just me." In addition to maintaining the belief that open source software is the best way to go, Torvalds is Finnish, married to a karate champion, and has a personal mascot that's a penguin named Tux, all of which make him pretty unique for this list.
