In the gathering storm against SCO's attempt to gather licensing revenues from Linux, IBM has upped the ante once again, filing an amended complaint against SCO asking for, among other things, a declaratory judgment that would explicitly prohibit SCO from imposing additional restrictions on software that it had released under the Gnu Public License (GPL).

IBM has also charged SCO with copyright violation on seven pieces of IBM software that the company claims SCO only had the right to use because of its adherence to the GPL and therefore by breaking the GPL, the company has forfeited its rights and is now subject to complaint from IBM for piracy.

Finally, IBM has also accused SCO of causing the company damage its dependence on promises made by SCO relative to the GPL that were not followed through by SCO.
