I have not used dating apps myself (have a single partner for 15y+ and generally was always meeting romantic interests through friends), but ~half of my friends got their partners through Tinder 5-10y ago. They were very happy with it - though this was in Europe, not in a tech hub. Two of my close friends who don't have partners and still use Tinder said that in the last few years, they became useless unless you are a spending whale (enshittification). Full of bots, full of people keeping to make new accounts to take advantage of boosts at the beginning of the profile, needing to spend money to get any matches after this start period. Basically bait-and-switch model and pay-to-win, but with romantic life and self esteem - sounds absolutely cruel.
