On the subject of free, cheap or paid. I do like the open source community for the mutual benefit virtuose circle it is.
Although, I am not shy of paying for something of good value be it commercial or community generated. I remember a friend’s father raving about his extremely well priced wine he bought a few cartons of at 69 cents a bottle. We sat and had a glass and all I could say was;
Its is low priced, but frankly I would spend more.
The main problem with proprietary software is when the licencing itself interferes with it use, for example if you want to test software in a Virtual machine, you should not need to pay again.
Microsoft addressed this somewhat through volume licencing agreement’s decades ago, at least for corporates. Fortunately Microsoft is much more enlightened now and provides a large volume of software and services, at little or no cost, free upgrades and much more. They are not perfect but nor are they as evil as they once were.
