Don't want to deal with Gnome? Plenty of other options out there like XFCE, Budgie, Cinnamon, MATE, KDE and many others. But yeah "Linux doesn't have a desktop that can contain folders".
I don't think this is a smart idea but they also aren't targeting the masses. They're targeting Linux users.
I'm in the boat where I may think this isn't that great of an idea, I don't care that Gnome is doing this. I don't put anything on my desktop and haven't in years. I used to hide it all on my Windows desktop too. I like a clean desktop with a beautiful wallpaper. When I'm at work and have to work on somebodies computer where their desktop is a shithole...it drives me insane.
No marketable or useable software that is used by the public depends upon third party installation for basic functionality. Linux has been, and continues to be, a bunch of developers who care more about their particular vision (not Linux's vision, just their personal vision).
And thats fine. Been using *Nix at work for years, I haven't even seen a Window system in many of those years since everything is CLI. But for somethinng like a UI manager, who's entire purpose is to MAKE software marketable... its baffling.
