Matrix still doesn't have a multi account client with threads.

I don't mind Matrix, but every time I bring this up to a hard core Matrix defender to how the clients are lacking, they don't have much to counter.

Sometimes even anything other than SMS kn the US because ppl just assume everyone have iPhones

Telcos know that authentication is about the only remaining use case for SMS and are not going to turn down the revenue stream.

And it can't die fast enough, as it's essentially the same as broadcasting your sensitive information over unencrypted radio.

Apart from security, phone number based user identification is such a half-assed approach and I still don't get why Signal wants to die on that hill. It's inconvenient, yet trivial, for anyone to register a second, third or tenth phone number. With a bit more knowledge and inconvenience, even anonymously. It adds so little.

... people just send SMS to random phone numbers?

Signal and DeltaChat, as well as Simplex and some others e2e communication solutions, are adequate from a technical point of view.

The main issue is always adoption. You can have the most convenient way to safely communicate with people, it'll be useless if nobody you're talking to wants to use it.

So, since Signal is very easy to set up and use as well as the most adopted, it's currently the best pick for regular conversations.

Been using Deltachat for about a year, so far so good. I dunno how secure it really is (never took the time to check) but it's been reliable. Multi-device was kinda quirky at first but has gotten better.

Signal good, I've never heard of Deltachat

Signal is fine for a drop-in WhatsApp replacement. I use it for chatting to my friends casually. For something you need more security for you could do encrypted emails as that doesn't require exchanging phone numbers, or ideally just arrange to meet up in-person and discuss things so you don't leave any kind of digital or paper trail.

Signal is pretty broken. A chat app shouldn’t require a SIM card & an iOS/Android device just to create & maintain an account (too bad Linux or KaiOS users or folks that otherwise don’t want a smart phone). Multi-devdice setups seem to have issues. The desktop app being Electron is a waste of resources. They still don’t want to support UnifiedPush while highly encouraging you download the app from the Google Play Store & send notification data thru Google-controlled FSM. There’s also the missing history of the server code which is probably has something to do with US intelligence injecting code.

Is it better than a lot of things, sure, but it should be put on a pedestal nor seen as exemplary for private chat in UI or philosophy.

I said Signal, meant to say Sessions

Deltachat is a clever idea that I wish it became more widespread.

XMPP is an old protocol. GTalk (google talk) and Whatsapp used it, then extended it, then didn't give back to the community. So here we are...

The problem with alternative protocols and apps and whatnot is that people are reluctant to change and won't try anything new if only 2-3 other people use that protocol/service. I can't even convince my best friends to use Signal, let alone XMPP.

https://joinjabber.org is also a good resource for learning about XMPP.
