Many people sympathetic to the free market are not at all sympathetic to open source. I used to be one of these people. It seemed to me that open source was doomed to failure: it cuts against the idea that innovation is more likely to occur when people exclusively own something. Yet the success of Wikipedia, Firefox, Thunderbird, and now the newer, more user-friendly versions of Linux means the old skeptical economic model is difficult to keep up. The open source world has upped its game, producing high-quality products that often beat closed source and more traditionally-designed products. Some will no doubt put their fingers in their ears, close their eyes and deny the reality. But it seems to me that when the economic model does not fit reality, it is time for a new model.
