The following article (Why The Open-Source Model Can Work In India) presents and interesting viewpoint about the coexistence between propriety and open source software. Note the "j-factor" and "g-factor".
In fact, Phatak thinks U.S. programmers' open-source approach has changed the world. "Americans may not realize this, but the [general public license] is one of their greatest contributions to the world," he says, explaining that the GPL allows open-source software to coexist with proprietary software.
He considers the coexistence crucial. "The whole world can't depend on open source," the scholar acknowledges. Moving forward, the software world will consist of both those who develop proprietary code and those who develop open-source code. The success of this model depends upon two things--what he calls the "g-factor" and the "j-factor."
"Proprietary vendors should avoid the g-factor and not become too greedy, otherwise people will choose open source," Phatak says. "And open-source developers should avoid the j-factor and not become jealous that someone else might be profiting from their work. They should be delighted that people are using it."
