conversely, look at companies like facebook, google, and walmart who have all made the decision to open source their code. software and non software companies alike recognize that contributing their work to the world adds value to their own product. i think in the future you will have more non technology first companies, like walmart, with strong software divisions promoting and funding open source software. they dont need to make money directly off selling the software when they can make money off what the software does.
