maybe you should think about not spilling company trade secrets to competitors. I'm not trying do defend Opera, but if an (ex) employee ( be it contractor or not) revealed or used the same thing that he developed for my company while i was paying him , i would probably sue him too. Now ... in this case there are a lot of missing facts, but in the general case, when it's about a lot of money , i think any sane CEO would decide to sue.
