Since its inception in 2014, dating appBumble's schtick was that women users "make the first move" — meaning, only women users can message male matches first, and within 24 hours of matching at that. Over the years, however, the concept has somewhat eroded.

It was always slippery for LGBTQ users, for example. Women can obviously message other women first, while men messaging other men would have to message first, too. Then in 2022, Bumble added more gender options which raised the question: Can nonbinary people message first, or only women? It turned out that Bumble allowed nonbinary users to message first.
