without *any* contribution
I'm not a lawyer. If I were, that phrase would give me a toehold or restless sleep depending on which side of the pile of money I was on...ok, actually if I was on the "hands on the money side", I would just advise avoiding the risk because that's what lawyers are expected to do.
Or to put it another way, the argument that works created by the program are not copyrightable might tend to be more expensive than simply paying licensing fees in a business context.But again, I'm not a lawyer.
