There's nothing paticularly odd about this.several of these operating systems will both notify you opportunistically of available open networks by default and make then visually distinctive. you then condition a user population to select then becuase they are open, and therefore don't require a cert, shared secret, username, password. and you get a scenario where it's going to get selected between meetings. unsurping since it's the low friction option. We tested the steps associated with with associating with an open wifi network on all the platforms we had available, and despite the notification that security might be good idea, it is always the lowest friction option.
