I’m not saying I like the current regime; I’m saying this ain’t the solution.
Much of the current internet is based on Free/Libre/Open Source Software at least somewhere in the stack. Of the world's top 10 most visited websites, at least one is 100% Creative Commons. Several others have large chunks of FLOSS in the software stack.
Feel free to disbelieve, but be aware that you've already been out-competed by people who DO participate in and/or make use of our digital commons (fairly or unfairly).
If we released our source code it would do absolutely nothing, since you don't have our business partners or customer base. All you could do is publish pages that look like ours
