Linus Torvalds on the tension between open source and intellectual property:
First off, even if you’re the smartest man on Earth, and you write something really interesting, it will take you years to do. In other words, it will take you time before it’s really even worth stealing. So if you start making it public early on, don’t worry about people and companies trying to steal your work. They’ll probably not even know about your work, and they’ll certainly not think that it’s worth stealing. And by the time it is worth misusing, the project is already well enough known that people can’t really misuse it on a big scale without getting caught.
