hi
it is using double ratchet but heres the most recent tob. the fact that they use distributed self hostable relays and no user identifiers is more secure imo
yeah it’s annoying, but they’re pretty committed to the no user id thing
yeah you can only use one device at a time because simplex doesn’t have accounts, just devices. but you can make another account per device and add them to your chats
4/5, and partially 1 bc mobcoin doesn’t use pow or pos.
disclaimer: I don’t fw signal or cryptocurrency of any kind
4 and 5, from what I remember you have to opt into being discoverable by number even if you give it your contacts. that said I don’t fw signal for the other reasons stated, it’s basically just the easiest secure alternative to texting.
most some of the stuff on that list isn’t even true (at least not anymore) lol
the meta stuff (fb messenger, ig, whatsapp) always have issues. bridges get flagged as bots, service goes down, etc
it’s probably the best p2p messenger out there
