I can see a few reasons: 1. It's a full-featured, widely tested desktop environment. If a user can't figure out how to enable Bluetooth in LXQt or there's screen tearing in Xfce, then they might blame your hardware. You especially also need someone to rely on, who does ARM builds, which many distros do, but fixing the build of the desktop environment often is something you need the help of the DE devs for. 2. It looks modern and polished. You can theme the more lightweight alternatives, but they often still have UI elements that are not correctly aligned and such. 3. The KDE Community is big, and many of them got the news of this Pinebook. If some buy it for themselves, or gift it to someone, or just tell their friends about it, that might very well be your first year of funding secured. 4. It is kind of news-worthy on its own that one of the most feature-rich OSs ships on one of the cheapest laptops.
