Two points on this.
1. I'd say about half my romantic partners have come from apps, and the other half from in person (meeting at parties, through friends, etc). TBH I'm not sure one has been consistently better than another. Sure meeting someone in person for five minutes tells you a lot about potential compatibility in ways that texting via app doesn't. However, how someone constructs their data profile tells you a lot about how they see themselves, which you might not get from meeting someone casually. Empirically, I wouldn't say the outcomes from one source have been consistently better.
2. I really don't think 'enshittification' is unique to dating apps. Look at the internet. Like, recipe sites now all tell you about how special this soup was to the author's grandma and how treasured her childhood memories are of it ... because you spend more time on the site and they can show you more ads. More search results are just low quality SEOd blogs and what not. Tons of software is moving to a service model, because they can get sweet MRR from you, and make more money in the long run. Food, social media, games, etc are all getting engineered to become more addicting. Like this is neo-liberalism.
