Data-Hungry Dating Apps Are Worse Than Ever for Your Privacy | Mozilla privacynotincluded

This is a most excellent place for technology news and articles.
Depends on how it is used. But I don't think it should be used for the matching process itself though. Maybe to help match interest (tags) between each other, like giving a connection score between two of them, but other than that, I see no other privacy respecting way to use that.
Moreover, on which data would we train on? I don't think there is any anonymized dating app dataset around.
