(As non-curmudgeonly as possible, this is a genuine question I promise!)

I see a bunch of projects and companies these days calling their product an ‘OS’. I'm not too much of a stick-in-the-mud to not see parallels between traditional OSes and things like Kubernetes (which actually doesn't brand itself as an OS, confusingly enough), but I'm genuinely very confused as to what it's supposed to signify in the branding of projects like these — e.g. this seems to just be a server that runs on Windows or Linux and provides a control panel for your UniFi devices and account. Could someone explain to me what the ‘OS’ is supposed to mean here? (Even if it's something very vague like ‘a sense of being a complete solution’!)
