psykocrime's Journal: IBM files new counter-claims against SCO in Linux case

According to this story at Smart Money, IBM has filed new claims against SCO, alleging violation of the GPL.

Quote from the article: According to the memo, which was obtained by The Wall Street Journal, the new counterclaim charges that SCO infringed IBM's copyrights by distributing IBM's contributions to Linux after SCO had violated its Linux license by claiming a copyright on parts of Linux.

At the least, this seems to be an encouraging sign regarding the validity of the GPL. After all, IBM's lawyers wouldn't be basing claims on it, if they didn't think it had "teeth."
