They spent years lying about their encryption algorithms too acting like they're more secure than Signal when they never were

I can only assume there's a different backdoor for 10 that just hasn't been published. Even if there isn't, Windows defaults to backing the key up to the attached Microsoft account. You think they'd ever tell intelligence agencies to come back with a warrant for that?

Just use Veracrypt folks.

Matrix, Session, SimpleX chat, Tox chat, Jami... and so on.

Signal still doesn’t support bots and is shit for bigger groups

Good for 1-10 friends and 1on1 chats tho

Same. Any non-verifyable app in an app store is at least suspect.

Why would you not trust Signal?

You don't have to trust their server infrastructure, because the end to end encryption has been verified by countless experts (and all their client side code can be looked at by anyone).

With WhatsApp I’m quite sure that they somehow can retrieve the private key. Certain events point to that.

What events point there?

The Kremlin doesn't buy, it takes.

Russia is a toothless tiger.

I think the point is not so mich whether you can trust Telegram or not (although I am shure you can't).

The issue with Telegram is, that (by default) it stores all your chats unencrypted on their servers. So they can just access every message of yours whenever they want. That is not only dangerous for privacy, but when their database gets hacked, there is a decent chance, that all of your chats are gonna be released. Also, if governments want access to Telegrams data, they are legally obligated to comply.

What you should look out for, when you want more privacy is:

1. Legit End-to-End encryption: That means, that all your messages are stored and transmitted encrypted and only you and the person, you are talking to have access to these keys. So even if the server of the messaging service, you use is malicious or the government forced the organisation, which is responsible for the messenger, it would be mathematically impossible to read any of your messages.

2. Open Source clients, that can be verified by security experts. End to End encryption doesn't mean much, when you can't verify what the service, you are using is doing with your private decryption keys. In other words: It isn't enough, if a company just says, they are doing encryption. The solution is Open Source clients, because that means, that everyone can see exactly what the apps are doing and can inspect the source code for backdoors or vulnerabilities. Usually, if a lot of people have been using them, you can be sure, that some experts have verified, that nothing fishy is going on.

If you want a simple suggestion, that has good encryption and is fully open source, but is still easy to use, I would suggest you go with Signal.

As in "with WhatsApp we know, with others we cannot exclude the possibility"?
