As SCO continues to move forward with their lawsuits, it seems that they are getting more and more desperate. Now, they are accusing IBM of destroying evidence. The accusation is that programmers working for IBM intentionally deleted source code that could have proven IBM's guilt in the copyright infringement claim against them. The original lawsuit against IBM was brought in 2003, and is going to trial sometime next year. SCO has still failed to produce any evidence that IBM used SCO's copyrighted code in any Linux application, but likely they will continue to push even harder as the deadline nears.
SCO has already had the majority of their claims against IBM dismissed. They are trying to get that dismissal reversed. Whether or not any IBM programmer deleted code is unknown, but if true would have serious implications for big blue.
