just search seytonic bluetooth on yt , you can find it preety easily ngl

is rare, but briar as you identified is pretty good. Though android only.

The trouble with peer to peer is it isn

theres also notification scandal recently which i think the op doesnt know about

speek sucks in my opinion , i tried it ,

tbh jami is the best app currently in the p2p messenging space

berty sounds good as well , its built on top of ipfs and weshgaurd

tox is good as well

(i have messaged briar and berty team regarding some questions and i havent gotten its answer , i will update you when i get the answer)

https://www.securemessagingapps.com/ if you see closely for session , it says that attachments are centralized in their servers in canada

session tries to promote their oxen cryptocurrency and lokinet which imo crypto currency are used by baiters to bait people into ruining their money

you dont understand what signal /molly is , do you ? they are centralized server and OP specificially asked not centralized server / server for that matter

matrix is good but it still need server , plus matrix.org takes quite a bit of metadata

jami’s good but it uses turn server to verify your name

briar’s bluetooth functionality can be violated plus no good ui/ux

vscodium just works for me , its just like vscode removing telemetry
