Because the MS parts are mashed together in a literal computer part sandwich, stuck it in a square, and slapped a fan on top of everything. Where is the airflow? A vast majority of the intake and exhaust holes are covered, either by internal parts, a rubber stand that can't be removed in a horizontal position, or some plastic green thing that serves no function. The heat sink on the Xbox XSX isn't that large.
The PS5 is a simple clean board, a massive heat sink that will prove to be very useful in dissipating heat and a large singular fan that will move air through the system on both sides. There is ample air flow designed into the system and it's not blocked. The stand is removable and looks great in either position, with thought put into the smallest details, such as how to store the single screw required for vertical position when it's in the horizontal position. For the Xbox, you push it over, and the stand just sticks out when it's on its side. Like you've put a blender on it's side and just don't care. For the PS5 It's attention to detail, similar to an Apple product, and it looks extremely well done.
I'm sorry, but comparatively speaking this design:
is absurd.
Uh ok. Not sure what you think you're accomplishing. You're just blasting aspersions but I'm explaining the difference in engineering approaches between the two systems and how obvious it is. You want to say I'm "bitter" for pointing out simple facts, so I just tossed it back your way to show it's silly.
If you actually have a point or something substantive to say, I'm all ears.
