So, some time ago, I was discussing how the open-source world was, in my opinion, lacking a software that keeps the “contribute source back” core principle of the GPL without being so convoluted and restrictive. I named the concept NPL (Neolander’s Public License) as a temporary name. Well, that side-project has grown up, and I can now show a first draft.
The current draft is now stored at https://theosperiment.wordpress.com/mosl/.
This draft is about 2 pages long, and I hope it will stay that way. For now, I wouldn’t recommend basing any software on it, since the text has not passed lawyer review to check for loopholes, and I lack a permanent hosting service to put a copy of the license on. But the overall spirit is there. So, do not hesitate to leave comments. And if you have a lawyer friend, please call him/her for help too !
