SCO's accusations against IBM and Linux's OS have raised many controversies from the moment they were made public.
The e-mail which confirms that Linux doesn't have any code lines that rightfully belong to SCO raises many questions.
Aside from the conflict that will build up between SCO and Groklaw, the site
that posted the e-mail, the real problem is related to the credibility SCO's officials will have from now on. Although they motivate the e-mail by saying that it had nothing to do with the lawsuit against IBM, keep in mind that in February, U.S. District Judge Dale Kimball criticized the lack of evidence SCO brought to support its accusations.
Will SCO be able to prove that they are entitled to receive $1 million dollars for copyright infringement? It remains to be seen what the justice will decide, but the damage done to company's image by this e-mail duel will be much bigger than any sum SCO is claiming from IBM.
And perhaps, others who are preparing lawsuits should be more thorough when formulating their allegations. On the other hand, a little publicity is always helpful.
