So basically this article makes a Kant-ian argument that we need rules to actually get freedom. I think that there's nothing wrong with that argument, but the whole story to make open source about freedom is not the right way at all. I think if you release source code for other people to use is more akin to a present you make for the whole society of the world, which may be able to advance itself with it. Presents shouldn't be bound to conditions. We certainly need rules for our societies, but they need to be part of the law, not part of some conditions of presents. That's why I release the stuff I write under public domain/CC0.
