If you think, people would come to Ubuntu just for the nostalgia for the Unity Look…especially the newcomers. Funny that you gave a link to that “senseless” thread!
Suru clones are nothing new in the Linux world. Had been there for years.
Using an unmaintained Desktop Icons extension by the original author as a system extension is also not going to help, which points to someone else’s extension in gnome-shell-extensions. The author names don’t match. This too is misleading. Install it in another distro and see what happens.
How nice to live in a world, where no one criticises!
