From Help define “open business”:
We started Openbusiness to share knowledge about business models that give a substantial portion of their main product away for free. By “free” we meant free as in “freedom” and also as in “free beer”, paraphrasing Richard Stallman’s famous illustration of the difference between “freed” from restrictions of intellectual property law and a product which literally costs nothing.
Everyone is free to edit the OpenBusiness Wiki. For more information, What is an OpenBusiness? is a good place to start.
