I don't think that in the Linux world people use something they don't like, unless there are no alternatives. In my case I don't like to have a top bar and that's one of the reasons I never considered buying a Mac since the 80s (the global menu is another one). So I kept using Gnome which let me move everything to a bottom bar (Gnome Fallback with GTK3). Gnome Shell seems to be able to do it too now and I'll give it another try when I'll upgrade to 18.04.
So yes, I never used Unity but I didn't ask for its demise. There were alternatives and I was happy with them. Still Canonical decided to dump Unity. Why? They couldn't make money out of it, and out of Mir and the old Convergence project. [1]

That's not because people were asking Canonical to kill Unity.
