Since grsecurity is delivered as a source code patch, it is not possible under the terms of the GPL to offer a free version under an actual restriction that it be used only for evaluation purposes. Any customer receiving a grsecurity patch receives all the GPL-granted rights and responsibilities, including the right to redistribute patches in their possession or even to sell them to others.
