I would rather say something different: dating apps have zero interest in making you find a partner- this means for them simply losing a customer. They would rather keep you in a cycle with some intermittent reward but preferably without losing you.
Finally there is an huge difference between different classes of users: at the very minimum by gender, attractiveness and purpose. Casual sex is a totally different use case than looking for a partner; high attractiveness allows using the app intermittently for immediate reward, while average people need to put much more effort and entirely different mode of use. But despite all this complexity, apps have converged to a single hyper-simplistic model that optimizes maybe intake of new 20 year old users but works much worse than it could for most people.
