Well, what unfree operating systems are there: * Windows * macOS * Android * iOS I think that is, at least for general purpose consumer level hardware, exhaustive. The article excludes macOS and by extension iOS. It also excludes Android, since it points out these are the same shenanigans pulled by Google. The only possibility, then, is Windows. Microsoft have root access to your system and can do an update whenever they want. There has been a back and forth about how much the end user can push back, but obviously Microsoft wins that battle. This is definitely a security benefit - but it also means you cannot check out the behavior of the system and have confidence about the behavior of the system tomorrow. So the answer is no. Anyway this is no surprise. Business have worked out they can rent you the things they used to sell you. Why wouldn't they?
