A lot of arch users are kids fucking with thinkpads ricing up their systems and putting anime wallppapers while not doing anything serious.
Ubuntu is commonly used by researchers and hardware developers who don’t really care about distro as long as it’s linux. The amount of times I saw people use the entire distro with default gnome skin just to launch a terminal to run their black hole simulation, the crypto cracker or some centrifuge control script… I myself am neither but ubuntu has been my go to as well since I usually don’t have time to screw with archinstall, so I just use ubuntu as good starting point and then tweak the internals as I go.
This is working as intended, though. In most cases, nobody cares how stoked you are about the product, people mostly care which flaws the product has. With a target average of, say, 4.5, the 5-star system gives you options to give +0.5 stars all the way down to -3.5, giving negative reviews significantly more weight.
