I've heard this theory before, and it doesn't make sense to me.

Finding a good match is hard. The vast majority of relationships fail, most of them rather quickly.

I don't think dating apps need to go out of their way to preserve their user base. It sounds as if people believe that there's some perfect matching algorithm that the dating apps refuse to use, lest everybody suddenly get married.

Male and female users do end up being in conflict on dating apps -- the former getting too little attention, the latter getting too much. And the apps are rife with spammers and scammers, which are hard to clear out when the accounts are free. I think that suffices to explain why people get frustrated with dating apps.
