I really would like to have one of these t-shirts. They say they took the idea from this video:
This is near and dear to my heart. You’ll notice that my books, articles, blog posts and even my images are all free to copy. I have chosen the Creative Commons License 3 (CC BY-SA 3.0) — asking that you let people know who did the work (attribute, the “BY” part) and that any modifications you make, you then share freely under the same license (share alike, the “SA” part). And the only real reason for using that license in particular is because of it’s widely recognized. The only reason I want attribution is, not so much for the recognition, but so folks who need something else in the same vein will at least have some idea who to ask for it. I have also released quite a few projects under public domain. It’s really a matter of conscience and conviction. I practice what I preach.
This is the virtual economy, and to some degree, the economy of the future. It’s also the essence of the most powerful weapons on this planet. Already, leaking secret stuff has become the ultimate weapon against oppression. One of the most enduring prophecies attached to tribulation and wrath is the principle that God exposes hidden sins. Let us pray that God continues to rip the cover off of dark places and shine His glory into every corner.
