I'm just not sure there's a real phenomenon here. People's complaints about dating apps match up pretty precisely with common complaints about dating more generally. It's an inherently frustrating process!

I think it's pretty telling that the alternatives people talk about are always alternative strategies for how to meet lots of people. The most common pre-app experience, where you didn't meet lots of people and married a random person in your social circles rather than a best friend who gets you and shares your key interests, isn't something most people are interested in.
