For the security I don't see anything listed about keeping the latest patches, although I don't see why they wouldn't. The article calls 16.04 ancient, but it's fully maintainable, so...
"unsupported". Do you mean on a mobile exclusively? I have no idea. IIRC, Ubuntu changed how LTS is maintained vs. licensed LTS, support itself isn't gone. Trust me, the little update center ("A") annoyingly lets me know EVERY DAY on my Gnome based 2-in-1.
Ubuntu+Gnome isn't dying, it's growing. It's poping up in videos all over the place covering all kinds of things, which usually are not about installing Ubuntu or even related to Linux at all. Somebody... somewhere... is making it trendy. "It", as in Ubuntu+Gnome straight vanilla style, also no other desktops like the superior KDE.
Biting the hand that feeds IT
