There’s nowhere near a reasonable number of users on Fediverse to sustain a geo-local dating app. Tinder already has to rate-limit matches so people don’t swipe through their entire dating pool in one day. You’d be better off turning to your geo-located communities on Lemmy and encouraging meet-ups or other ways to connect.
Fediverse is open source and decentralized, so any for-profit model could leverage it without asking for anyone’s permission. There are already for-profit companies that build and maintain apps to access Fediverse platforms. Meta Threads and Tumblr are both integrating into ActivityPub as their own hosts. I imagine in a future where Fediverse grows rampantly, the hosts with the best overall user experience will be for-profit. We live in a world of global capitalism, good things cost money most of the time.
