IIRC, OkC also removed the ability to bookmark profiles, presumably for the same reason -- everything moving to a more "ephermeral" experience to prevent anybody getting "obsessed" with certain accounts because of how creepy that gets. Since spam, stalking, and abusive messages are by far the #1 problem with any online dating service. (Yes blocking works, but it's even better when people don't have to block in the first place. If you have to block too much, you quit the app.)
Presumably this means advertisers.
I used OKC for years until the founders sold it (and my private data) to this shady company, then I was forced to delete.
Acquisitions are worse than breaches for end user privacy. GitHub sold your whole travel history (via client IP geolocation) to Microsoft.
