Bluetooth ranges are quite large now.
But an example even if someone is a foot away would be a concert or event where it’s to loud.

If you’re in Bluetooth range can’t you chat with your mouths? Or is it for secretly chatting when you’re in a group of people? I don’t get the use case.

Could be useful on a plane: If you have different seats than someone and don’t want to pay for your airline’s ridiculous data prices. Although, most airlines I fly on(american, delta, air canada, united) all have free RCS/Facebook/Whatsapp, but not necessarily Signal, Telegram, Matrix, or your preferred secure service.

I have no idea if this is correct. But imagine if you have a setup like Apple’s AirTag. Except when you receive a signal (message) you also relay it to whoever’s path you cross for the next X amount of time. The more people using the app the bigger the mesh network gets.

It’s not about you being in bluetooth range of the person you want to talk to, it’s about all the people sitting in between you both that pass the message along without touching the internet.
So you can be on a cargo ship, or on a remote island, with 20 other people and all use chat. If 1 person has internet, then you can all chat globally as well.
It’s the same basic method of how airtags work. Everyone with an iPhone connects to the airtag and passes data to Apple. It’s just done in the background, so users don’t ever notice.
