There is a language picker on the site which seems to give these translations. I'm also not 100% sure if the English version was the original version either, or at least it would explain some of the word choices if it wasn't.
It's static. There's a dropdown near bottom left to switch back to en-US. Looks like most of non-English versions are machine translated, except not all from the same singular version.
Eine freundliche Distribution. Ok, fuck yes, if it is friendly, does it say good morning and good night? And ask me how I am?
"Es ist eine perfekte Kombination aus Erfahrung und Ökologie." Ok, it's about ecology, so something about trees and nature and owls and bunnies?
"AnduinOS ist Ihre finale Linux-Distribution!". Wait, you'll think I DIE if I use this?
