I don't think comparing the dating app to a pizza restaurant makes the dating app argument fall apart. The difference is that even a satisfied customer will get hungry again, so it's possible to provide a really good experience and still have that customer come back. A dating app is unique (or, at least in a different category) in that the best possible outcome for the user (assuming monogamy) is that the user deletes the app and never uses it again.

More fundamentally--if a good product keeps a customer coming back for more there's an incentive to provide a good product. If a happy customer doesn't have any reason to come back there's no value in creating a happy customer.

Note that "come back" needs to be interpreted broadly. For example, a Osprey backpack--lifetime warranty against most anything, doesn't look like there's any space for repeat customers. But--those of us who would buy something like that very well might want different sizes. And I would certainly recommend them to others who were in the market for a serious backpack. (And, yes, they do honor the warranty--had a buckle snap, I sent them pictures, they offered to repair it, or ship me the part and I do it myself. Took the latter option, a few days later I had a strap and buckle that I threaded through my pack, good as new other than the color didn't match.)

I'm sure I've read that there's one where that is the advertising tagline, something like "The dating app you're going to delete!"

Pretty strong statement to be honest, I wish I'd thought of that.

It's like any other "problem solver service". There's always an incentive to farm repeat business.

luckily for the opportunists that make products that capitalize on human psychology for profit, strict monogamy for life with one individual is not natural!
