They’re fine when they’re actually designed to help people meet people they’ll probably like and go on dates. In the good old bad old days when the science and practice of monetization was far less refined the then-existing dating websites worked okay. OkCupid had no swiping or anything. You just answered a few dozen questions about stuff you liked and didn’t like and believed in, and then the website would show you a weighted list of people with answers similar to yours. That was it. That was the whole thing. “Hey, this person also likes gophers, thinks golf is dumb, and prefers dancing to sports bars. You probably won’t hate each other, send a msg”. It wasn’t magic or anything, but it was fine and worked okay. The enshittification really started with Tinder. Gindr worked fine because there were enough gay men who wanted a hook-up app that it’d support itself, but that dynamic wasn’t nearly as sustainable with straight people so Tinder kind of did a death march towards monetization and dragged all the other online dating stuff with it.
