I agree that there are probably more users of Discord and yt-dlp outside of the computer field than Debian users. However, people who use computers do use an operating system, and typically have/require somebody that they ask for help when they can't fix it. The question was, why Debian on a Desktop. Like other commenters, I had great success moving people to Debian because all they need nowadays is a browser, and it requires a lot less maintenance (by themselves or third parties) than other distributions. Most "ordinary" people just want their system to stay the same, and are not enjoying constantly having to adapt to new UIs.
