> This is a bit too conspiratorial: I've spoken to people who work at these companies, and there's not a team of analysts trying to figure out how to minimize the number of successful relationships that come from using the app.

I think the effect can be true without anyone having ill intent. The dating app companies are generally trying to make as much money as they can, which will indrectly lead to decisions that optimize for serial dating.

As a parallel I don't think Facebook is full of evil people who want to increase the amount of hate and anger in the world, but it does have a lot of people who just want to make money and encouraging negative reactions happens to be an effective way of doing that, so that's what we get.
