It's not just dating platforms that have changed, it's also the users. Online dating used to be a niche you had to actively seek out, which meant that the users were naturally self-selected, had more interesting (for better or worse) personalities, and were (on average) more genuine.

Online dating today is far too mainstream for those qualities to remain. Any new dating platform that gains enough popularity to be useful will be quickly flooded with less-differentiated "normies" that dilute any quality in the platform's demographic, and the "optimizers" who game the platform at the cost of other users' experience.
