@boo_ It didn't really die, but I think it's between Haiku and the BSDs, definitely lost a lot and for a quite corporate OS (like you get some kind of SysV+BSD mix) I'm not sure sure about it being kept by hobbyists when the few corporations backing it will likely move to something else.

At least I stopped using OpenSolaris/OpenIndiana around 2013 while it was my daily driver desktop system since ~2008.

I'm more glad that ZFS and dtrace made it to FreeBSD, ZFS made it to Linux as well.
LibreOffice is still there.
(And Oracle vs. Google on Java is horribly disgusting…)
