The definitions of almost everything in our lives change over time. I would want to be practical and live in a world where words don't only mean what they used to when they were created but also are revised. Open source is a philosophy which I have always admired and it motivated my way of thinking. But I can not accept that a few large corporations want to apply their monopoly and scale to single handedly reap the benifits. Stopping them is vitally important to preserve those exact freedoms that open source gives us. The Open source movement was not created in an environment where there was such massive centralisation of computing resources and their financial implications. How do you know if the Open source movement itself wouldn't have started differently in an environment like today's?
