The downvotes might be for the slightly bombastic tone. SmartOs and IllumOS never felt “massive” to me, particularly compared to Linux. They might have had some nice tooling inherited from Solaris, but they were never particularly appealing for people who were not invested in the Solaris ecosystem - which had already been effectively wiped out by Linux by the time IllumOS and SmartOs appeared.
Or maybe the downvotes are related to the rather fanatic behaviour of some readers of this thread – I got downvoted for mentioning I hadn’t heard of those OSes, only to be then voted up; and downvoted elsewhere when I told somebody to cheer up because they had been downvoted for essentially making the same comment. It’s pretty frustrating, to be honest: “try to cheer somebody up, get punished for it” isn’t the way things are meant to be.
