The document discusses dark patterns, which are user interfaces designed to trick users into actions that are not in their best interest. It provides examples of dark patterns such as forced continuity that rolls a free trial into a paid subscription without the user's consent, notification nightmares that bombard users with notifications, and manipulation of reviews to hide negative feedback. While dark patterns can increase short term metrics, they damage brands over the long run and erode user trust. The document advocates for transparency and putting users in control to avoid dark patterns.
