No. The difference is an operating system that isn't a service means I, the owner, get to control how and when it updates, what services it runs, when they run, and even how they run. When an OS, or anything else really, is offered as a service those privileges are removed from me, the would-be owner, and instead managed by a third party. Sure, i might be able to select the level of service i want, but in the end the administration of it is beyond my control. I do not like that something I buy with the express intent of me being the owner of it is treated as a service.
no, I didn't buy it, but that's why I do not like the idea of an OS being a service
