I mean, social media and so many other contemporary internet products are engineered to be addictive, but that's to juice the revenue of their parent companies because their sole revenue is often advertising and addiction keeps people in their services longer and more frequently. It isn't a natural, innate feature of having, for example, a website where you and your friends share photos, make plans, and post things for one another to see. The addictive elements are almost universally the "gamification" of those services.
I think it's perfectly a solvable problem to have a social media service that performs all the jobs the users would want, while not pounding dopamine out of their brains continuously to make sure they never want to put their phones down.
