Open Source is about business practice, not ideology. Open Source is neither liberal nor conservative. It is neither externally owned or governmentally supervised. And it is far more about free markets than free stuff. It is the philosophical essence of capitalism in action... This white paper will examine the long-term problems of the traditional software industry and its customers, the paradigm shift in the creation, distribution and consumption of software, and the driving forces behind the changes that are enveloping the marketplace. We will discuss how, why and where Open Source is having such a dramatic impact, and how enterprises all over the world are moving to the Open Source model as the foundation for their 21st-century business models.
