Absolutely wrong. A lot of old and dated information in your post.

They have something no one else has: manufacturing, and very low price and great performance after recent driver updates. They just lack the driver stability which has been making leaps and bounds.

It sounds entirely like FUD. In my opinion Plasma wayland is prettier, far more simple, and much more mature than Windows. Windows feels old, clunky & now uses dark design as part of its UX.
