That was sort of my reaction to the article too, like the assumption that "your users want to pair up such as to stop using your app" is an obviously incorrect assumption in many cases. It also occurred to me that there's also an obvious expansion, which is into couples relationship and sex coaching/therapy/tools. I did some data analysis work with an app company with a lot of parallels to dating apps, and they kind of went that way: they figured out the needs of their users after their initial app was "done" and then offered another app, or expanded app to cover their subsequent needs. They actually did this twice very successfully, by branching out after a major stage of user need, that was the focus of the existing app, had been reached. These dating companies could easily turn into relationship coaching or therapy or relationship tool apps. There's plenty of possibilities.
