The Ethics of Open Source

Can a developer be expected to give away the Intellectual Property which may be a means of providing for his family? Open source software most certainly has its place on the internet, it allows communities to grow and improve a software together.This  encourages the application of technology to the society for the common good. Free software is a worthwhile philosophy, one which I find myself being involved in from time to time. I do, however, believe that just as a writer of a novel is entitled to the exclusive rights of what he develops, a software creator is entitled to exclusive rights of  the code he has written. Pressuring a developer to release his source code is like pressuring an artist to put their music up on the internet for free or asking an author to release his book at no charge. Just as the musicians and the authors are, for the most part, in the business to make money, likewise, for the most part, the software programmer is in the software industry to make a living.
