Eso es lo que yo pienso. Las personas cercanas a mi de verdad, mantenemos la comunicación igualmente. El resto, eran personas que sobraban. Me ha abierto los ojos mucho no tener nada de meta. Ahora tengo menos contactos, más verdaderos. En mi caso uso Session. Solo se lo han descargado 4 personas. Las justas y necesarias. Y para las demás, llamada de toda la vida. No he probado signal pero tengo entendido que es centralizado y el servidor no es open source. Y que si realmente lo querías open source tenias que montar un servidor y aun así no iba a poder hablar con todo el mundo. Y simplex no lo he probado pero no se si es tan seguro como session.
Telegram is "I was taken hostage by Macron, but I didn't agree to collaborate, he just randomly let me go". And it syncs between multiple devices, saving in the cloud. Signal is, as you say, "trust me bro". Content likely secure, metadata... depends how much we want to trust. Simplex, now, simplex where its at. I have all three, for different levels of security
Get out of Nostr world. Bitchat is useless save for local mesh network communication, and is extremely poor for locational privacy due to always having Bluetooth LE always on. Nostr DMs and White Noise basically shotgun your metadata across a bunch of relays, poor for timing analysis, giant metadata leaks. SimpleX is the golden goose with ephemeral one time chat links and multi hop asymmetric chat relays. It has nearly impeccable metadata obfuscation. Session is pretty good, a good chunk better than XMPP mainly in metadata obfuscation from individual relay runners and from a network observer. XMPP is okay, good e2e but only when OMEMO is enabled. Poor metadata privacy from a network observer and from a server operator. Really good for LAN messaging though, and a super simple protocol, easy to integrate aside email servers since addresses are of the same format. Matrix has a bunch of known issues relating to metadata and data leaks and has the same weaknesses of XMPP. Signal has WhatsApp UX with strong encryption guarantees and some degree of metadata obfuscation. Big weakness in the phone number requirement.
