You can't run X11 programs on Wayland without Xwayland.
Likewise you cannot run Wayland programs on X11 without a wayland compositor like Cage (a wayland kiosk) or Weston. Both run as a window on X11 inside of which Waydroid works just fine.
It's an odd complaint that incompatible software is incompatible.
I did. I agree it's not obvious.
But you cannot run OpenGL, Vulkan, Glide or DirectX on Windows either without having the proper hardware and software installed.
So yeah. Waydroid needs wayland. Anbox runs on X11.

Windows will run at least basic OpenGL and DirectX in software if you don't have hardware to accelerate that, and those software renderers are included as part of the OS. It'll run like garbage, but it will run.
Bluestacks works fine for this on PC and Mac, and I've seen casuals use that because they want to play their gacha game on a bigger screen.
Waydroid compleatly fails in comparison, while giving you no pointers on what the problem might be or how to solve it unless you're already a Linux power user.
