The userspace is so diluted now that it’s basically flat out wrong to say it’s just ‘GNU’, I mean Systemd is probably an even bigger a part than GNU is now, and we’ve long had things like OpenSSH from BSD as pretty core parts of the system, and we’re not going to start calling a distribution ‘Kubuntu Linux/Systemd/GNU/BSD/KDE’ or whatever… Basically about all something needs to be to be called an OS is a kernel and at least one userspace program that does something useful, so I’d definitely say every ‘Linux distribution’ has always counted as an operating system in itself (so ‘Linux distribution’ is just a specific subset of ‘operating systems’).
