When you buy diapers you are paying for the manufacturing cost and the profit margin. When you use Meta's products, what are you paying for? That's what makes them closer to cigarettes. Tobacco companies sold a lie to their customers.
Meta too sells the lie that its products are paid for by ads. Its products are paid for by surveilling users, building behavioral profiles from the data that is collected, and then giving other companies access to that behavioral data in order to manipulate users to specific ends. In this quest to build better behavioral profiles, the products are made to be as addictive as possible, eating away people's time which could have been utilized in objectively better ways.
