CS have given another company permission to sell their product in a boxed version. (copyrighted 2008 CS as stated on the box). CS collects money for every sold boxed version too. so they are indirectly responsible.
If they aren't feelin' responsible they wouldn't have given any update to another company.
So for now, after having no more contract with another company, your statement "but CS...basis" will be true
