Does anyone know how this compares to Freenet? The FAQ talks about it a bit [ https://gnunet.org/faq/10 ] but for example, I don't understand what "Economics" means in this context?
If GNUnet is like other file sharing, you share files while you are online, responding to searches and transferring files that are requested.
Short and giving a clue as to function and freedom the name seems a good choice to me. The (GNU) GPL insures that the users and community will not be restricted from making their own fixes or enhancements. I think it is misleading when some refer to a permissive license as restrictive. You're given permission to do practically anything to the code for your own use, and basically have permission to distribute it to others too as long as you DON'T impose new restrictions on them.
