Things are confusing because Xinuos recently launched a brand new lawsuit against IBM and IBM owned RedHat. Xinuos' claims in that case are all about anti-competitive behavior and nothing about TSG's historical accusations of code theft and breach of contract. I'd actually say the lawsuit is about Xinuos' failed business model: * The infamous SCO vs Novell & IBM lawsuit soured everyone on SCO, so companies got their software off of OpenServer/UnixWare as quickly as they could. * Those few who continue to use SCO products have existing OS & user licenses that will remain valid in perpetuity (or until the 2038 bug renders them unusable), and virtualization allows continued use of those old OSes on modern hardware without help from Xinuos. * Their "V" (VMWare virtualization) releases amount to pre-installed disk drivers and small performance tweaks, and for that they switched to an annual subscription model that it seems nobody will buy-in to. * Some of their releases like OpenServer 6 broke some backwards compatibility. Newer releases like OpenServer 10 are just rebadged FreeBSD with a bit of SCO legacy binary compatibility thrown-in. * The ascendancy of Linux made SCO and Xinuos' expensive commercial OS products increasingly irrelevant before the IBM/Novell lawsuits, and only ever more so today.
