Perhaps a different monetization model would fix that. The ideal outcome of a dating app for you, the user, is that you find someone to marry and spend the rest of your life with, and that means you won't need the app anymore. This means that for apps where the user is a source of ongoing revenue (either paying directly, or through ads), there is an perverse incentive for the app to want exactly what you said. An idea I've heard before would be an app where there's a one-time payment to join, and that's the only revenue ever generated by each user. Then their incentives would be aligned with yours.
