Dating apps are designed to extract as much profit from the user as possible. So the dating apps are actually working as intended if your cousin isn't getting any dates. They promote unhealthy objectification of other people through their systems and also are incredibly monetized. On the computing side, they are centralized network services that no one except the corporation has any ability to inspect. The apps themselves are also nonfree software that are filled with spyware and targeted advertising. In a capitalist society, dating has become another market for capitalists to exploit.

Everyone laughed at people who used dating apps without actually reckoning with why these apps were so popular in the first place, now future generations will have to suffer without ever knowing a world where those apps didn't exist.

All is to say, I'm glad you're supporting your cousin as much as possible.
