Yes everyone wants to sell more, but social media companies purposefully try to make their product addictive. There are entire teams of psychologists and behavioral experts figuring out how to maximize engagement through manipulating your emotional response to stimuli.
It’s similar to the superstimulus effect in junk food. The stuff is designed to hijack your instincts without providing much in return. We think we get more value out of social media (or a bag of chips) than we actually do because it’s purposefully designed to make us feel that way.
This is the intention of capitalism - profits go to the companies who can build products that people are most enticed to buy. A company that doesn't work to make their product loved/addictive will not continue to exist.
Another way of phrasing what you've said is that we should prevent companies from building products that people really like and want to use. No one is forcing anyone to use Facebook.
