The point of the free software movement, and the licenses, is to make sure that in the future, they will still be free software. It's the Paradox of tolerance[0], expressed in legal language, for software source code. Digital goods, while often posing as tangible goods, actually have near zero replication cost, unlike tangible goods. This, combined with the special circumstances provided by free software licenses, enable a special economy, where the barrier to entry is the lowest possible, and the contributions to it are maximized for further enabling the special economy, for all current, and future participants.
