Social changes have caused chaos. A lot of the "traditional" dating methods existed to give structure to finding a partner. Unfortunately, those structures got trashed by the general update to gender roles. While these changes are great in many ways, it left young people in limbo. It was eventually replaced with online dating, for many. Unfortunately, that, in turn has been trashed by corporate takeover.
You've also got the outlier problem. The problematic men and women make up a small proportion of the population, but do a disproportionate amount of dating. A lot of the complaints are aimed at the problematic groups. Unfortunately, they don't care. It's mostly the non-problematic people who get the wrong message.
