Because Linux and Windows users ask for different things than Mac users.

With 2560x1440 display, you won't get fullhd@2x sized desktop (scale 133%) on Apple. That something expected in Linux or Windows, but Apple will get you at most 1680x1050@2x (152%, they're 16:10, so different height) here.

It is compounded by the issue, that Apple traditionally used 72 dpi for @1x scale, while Windows and Linux used 96 dpi. Apple apps look quite good at lower resolutions, while Linux (ok, Gnome) dug itself into a hole and looks good on dpis much higher than 96. For Apple, it is acceptable to run 2880x1900 or 3360x2100 on 2560x1600 display, but when Gnome looks passable on 1600x900@1x, good on 1920x1080@1x and you've got 2560x1440, so you need to display 4K (1920x1080@2x) logical resolution on that... that's more "interesting".
