Every time the app successfully matches two people well enough that they form a long-term commitment to each other, that is a step in the right direction. When the app instead matches people adequately enough for a short-term relationship but keeps them coming back to the app for more, that aggravates the problem.

Possibly, the commercial incentives of these apps have them deliberately optimizing for short-term matches. Or it may be the case that the apps are doing as best as they can manage and the problem is simply very difficult to solve. If the former is the case, then removing or regulating the commercial incentive might help.
