Because most people who use Reddit on a semi-regular basis use their old desktop UI (old.reddit.com), which doesn’t have the dark patterns found on their newer / mobile site. It’s a much more usable site for the few communities I still have left on Reddit. It’s also much better supported by the individual subreddits via style sheets (most didn’t bother updating layouts when Reddit introduced a new UI because all the power users who would have updated them kept using the old interface).
