The problem is that getting to that point requires quite a bit of capital. The hard part isn’t building the app, it’s buying users, largely through advertising, and then filtering the assholes through moderation staffing. Both of that costs a lot of money, up front. To date, nobody has come up with a way to monetize dating apps in a way that doesn’t negate the benefits of the app.

Personally I’d love to see someone figure out a way to do an activitypub based dating app, where people can build small community instances funded directly by the users.
