There’s nothing wrong with designing an addictive product. The more important question to ask is how that product impacts the people who are addicted to it.

Good Example: Notion is INSANELY addictive. But because they’re not selling ads, they use design to help people be more productive. Their motive is honest and positive. They don’t care whether you use the app for two minutes per week or two hours per day, as long as it’s benefiting your life.

Bad Example: Facebook’s whole motive is dishonest and evil. They want to waste as much of your time as humanly possible so they can sell more ads. I don’t even check my notifications anymore because it’s usually some BS that isn’t even a “notification”—just them trying to manipulate you into staying on the app longer. The problem is widespread, and it doesn’t all fall on the shoulders of designers, but they do bear part of the blame. To suggest otherwise is simply nuts.
