Open source software

In our discussions about open source software, it has boggled my mind how people could think that open-source software is how the industry should go. I think there is a definite place for it and it is definitely beneficial to the industry as a whole. I think of it kind of as the printed word industry. Books, articles, and other printed forms of writing are copyrighted, so that other people can't take credit for the work. Even thinks that are loosely based on copyrighted material can be punished. That is how software should be. If a developer doesn't want their source code to be open, they shouldn't have to have it open. It is their property and they have the right to protect that. That being said, if people want to release their own stuff to the open, that's their prerogative.
