We strongly believe in the principles of the free market. Government developed, free software has no connection with this because there are simply no customers, only users. A government allocates some money, which is spent developing a piece of software. Then the software is made available to any and all at no cost. So users can download it and some may even say they like it, which is a relative term. But unless they are willing to vote with their dollars, prospective users have no real indication that the software is viable. So in essence, you get what you pay for. We are happy to pay for the software we use. The fact that others continue to purchase the same software we use gives us continuing assurance of its viability and quality. Our own clients continue to retain us for engineering services for a similar reason; they know that the mere fact that we stay in business implies others use us and are happy with our services. Basically, it's a testament to the success of capitalism.
