I found myself on Debian‘s website today for the first time ever, I think. This is weird considering I’m a big supporter of their philosophy. Nonetheless, they had some inspiring words on free software. The quote below is an example, but the whole page deserves a read to be honest.
Software that is free only in the sense that you don’t need to pay to use it is hardly free at all. You may be forbidden to pass it on, and you are almost certainly prevented from improving it. Software licensed at no cost is usually a weapon in a marketing campaign to promote a related product or to drive a smaller competitor out of business. There is no guarantee that it will stay free.
