But if the GPL is not a valid and effective copyright permission, by what right is SCO distributing the copyrighted works of Linux's contributors, and the authors of all the other copyrighted software it currently purports to distribute under GPL? IBM's counterclaim against SCO raises that question with respect to IBM's contributions to the Linux kernel. Under GPL section 6, no redistributor of GPL'd code can add any terms to the license; SCO has demanded that parties using the Linux kernel buy an additional license from it, and conform to additional terms. Under GPL section 4, anyone who violates GPL automatically loses the right to distribute the work as to which it is violating. IBM therefore rightly claims that SCO has no permission to distribute the kernel, and is infringing not only its copyrights, but those of all kernel contributors. Unless SCO can show that the GPL is a valid form of permission, and that it has never violated that permission's terms, it loses the counterclaim, and should be answerable in damages not only to IBM but to all kernel contributors.
