I don't know, in the consumer market only Microsoft still sells an operating system but it's dirt cheap, you can get Windows licenses for a few bucks. The problem is perhaps rather that they don't sell operating systems and instead of building a good OS product sell their users' data or use the OS to lock costumers into their platform and hardware. There does not seem to be a competitive OS market at all (and probably there never was a healthy one to speak of).
