Who cares.
The GPL was designed so that any modification of a GPL'd work would eventually be free/open to all. All of us who have contributed to Free Software care; because Free/Opensource software was built with a "we're all in this together" mindset. I make xYZ program, you make C and D, other make W M V etc; and we have a free and open system at the end of the day.
It only works if everyone believes that their work will remain open and free: and that derivatives: changes to their work: will be aswell: because that is the "payment".
Payment /IN KIND/
Grsecurity is violating that.
It modifys a GPL'd work 1000s have contributed to (both the Linux Kernel and GCC) and closes it.
Now: I know you fucking piece of shit think that it's "allowed" to do that "because it did the WORK!". But you are WRONG. Because it based it's work on SOMEONE ELSES FUCKING WORK. The person who made the ORIGINAL work sets the terms of use for his original work. YOU MAY NOT USE IT AT ALL, NOR MAKE ANY MODIFICATIONS OTHERWISE AT ALL. The GPL states: No additional terms. No restrictions on distributees other than GPL.
Section 101 of the US Copyright Act
A work consisting of editorial revisions, annotations, elaborations, or other modifications which, as a whole, represent an original work of authorship, is a "derivative work."

Right to Prepare Derivative WorksOnly the owner of copyright in a work has the right to pre-pare, or to authorize someone else to create, an adaptation of that work. The owner of a copyright is generally the author or someone who has obtained the exclusive rights from the author. In any case where a copyrighted work is used without the permission of the copyright owner, copyright protection will not extend to any part of the work in which such mate-rial has been used unlawfully. The unauthorized adaptation of a work may constitute copyright infringement.
