You'll note that ReiserFS anticipated the GNU GPL V3 by including clauses that forbid removal of credits in its license, and for a long time I have been telling Stallman that he needs to get V3 of the GPL out the door.
By the way, does Debian support as a matter of principle the decrediting of Stallman and KDE by RedHat? I had really expected this from RedHat, not Debian, when I wrote those clauses.
In the academic world, this is called plagiarism. In the academic world, knowledge is shared but fairly credited. The GPL is born of the academic tradition.
