Signal is open source, you and anyone else can inspect the code. You can then build it from source and install on your android directly avoiding the play store.
So how do I build the Signal server and confirm it's identical to the one they're running?

#72It's important to note that Telegram does store all your data by default as they do not enable E2EE for everything like Signal does. So if you're under the assumption that they don't, this is incorrect. Telegram, for all intents and purposes, is about as secure as using Facebook. The best you can do with Telegram is hope they don't sell out or get compromised at some point in the future, because all your private comm…
The way I've been presenting it to people is that Telegram can look at more data than WhatsApp can. But WhatsApp will use the data they have more than Telegram will. That's the tradeoff.
And yes, obviously Signal is more secure than both of them but I've been steering non-techies to Telegram because of usability, backups, cross-device history etc. As usual, everything is a tradeoff, but if people were happily using WhatsApp up until now, and also use Gmail, Telegram is not worse than those.

#73After that, what data do you care about? Neither Signal or Telegram is intended to provide complete anonymity. That is a much harder problem. For Mozilla that would involve Tor. I don't think that Mozilla really has "servers" in the sense you mean.

#74What prevents Google from replacing Signal on the Android Application store with their custom and backdoored version ? Can we check a hash or something ? Does the signal foundation do that on a regular basis ?
That said, Signal does apparently support reproducible builds so that people can check that the apk matches what’s on GitHub (though this is more of a way to detect malfeasance on Signal’s part rather than Google’s)

#75We don't know that Signal doesn't store data about users on its servers. Even the source code can't tell us that, because we don't run the servers. What we do know is that programs like Telegram have to store data about users on their servers, by design. A big difference between the two projects is that Signal is carefully designed to minimize the amount of data the service needs to operate; it's why identifiers are…

#76Earlier quoted context omitted.
PIA used to be my go-to, but I immediately ceased using PIA after the 2019 acquisition by Kape Technologies, which has a rather foul track record.
What did you switch to?

It doesn't matter if it's not. Security should depend completely on the clients. Public-key crypto allows private communication through insecure channels.
No, it does. In some cases (think dictatorship) - you not only want the secret police to not read your messages - you don't want them to know at all, who are you talking to(and how often and when!). Otherwise you might all go to jail (or worse), if they are after one contact of yours. And then you can try to feel save, that they don't know your encryption password. https://xkcd.com/538/
not allowed to use VPNs because national security issues.

In a way, yes, Telegram is even less secure than WhatsApp for this. The way I've been presenting it to people is that Telegram can look at more data than WhatsApp can.

I think you should look at the odds of that "can" turning into a "will" over time. After an acquisition, or a change in business fortunes, or a change in leadership...

I can't trust any company that has to read my contact list PERIOD! It's not something anyone should be having to share ever.
