Because it renders the sky as a sphere, which looks ok at relatively horizontal levels, but not when you see the tops or the bottoms like this.
Older ports like EDGE also did this, but didn't fog the top or bottoms like GzDoom does, thus you see all the converging ponts, so it looks a million times more like shit.

It's sort of the same thing as Mercator Projection for world maps, the rectangular texture does not scale or fit appropriately to the surface of a sphere.
