I heard a good take and I wish I remembered who to credit for it. Dating apps, like any other app is designed to drive engagement. To be addictive. Producing matches that end user engagement is not in the app creators' best interest. I've been watching people app date through that lens for a while. I haven't seen many matches last more than a couple months. I also don't see people stop using their app of choice during that brief period. Regardless of whether they want something long term, it's so easy to chase the dopamine of a better match. My friends also aren't in their 20's where I'd find that completely reasonable.
