End->(public network)->WhatsApp->(public network)->End
So, no stranger can read it.
The key word is stranger. WhatsApp made the encryption you’re using and could (and I’m sure does) have the ability to decrypt it.
True end to end is where you and your partner have keys and you both encrypt on the client side, and don’t tell the middle man. That way no malicious intent from the server could ever decrypt the actual message.
That's how the Signal protocol they're using is working
WhatsApp is not peer to peer.
Nobody said it was?
What is it you thought they were saying?
You seem confused. E2EE doesn't mean peer-to-peer. Signal protocol isn't peer-to-peer. You don't need to be peer-to-peer to have secure communication because E2EE makes it so that the server can't read what the two ends are writing.
Can you prove to me that WhatsApp actually encrypts the message on the phone in such a way that WhatsApp can’t see the message when it’s on their server?
Do you truly believe a company owned by Meta would provide that kind of security from THEM? A company whose income is profiting on DATA supplied by users?
Tell me you believe this.
We know they certainly implemented it at one point. So it's not a big ask to do that for Messenger. And like someone said, would probably benefit them too since don't have to give info they don't have. But with it being closed source, it can't be verified if they're using it now.
Do you believe that Meta, if given the opportunity, would choose personal privacy over making money? It’s an easy yes, or no question to answer. 
What money?
Just money. Yes or no.
I need to know what your question means to answer it. What money are we talking about?
I’m not Meta, so I can’t give you a detailed breakdown of how they use the data they collect to make money. So, let’s assume by money I just mean money from their many sources. It’s a pretty easy question with only one answer.
But you are talking about what sort of money, something they'd get from not using E2EE?
Something they’d get from being able to read messages.
I guess it depends how much. If they'll net like a billion from not doing E2EE then yeah absolutely. If it's significantly less they'd might still go with E2EE for the PR and not having to comply with shit. It's not like they'd lose all the metadata anyway.
Let me be sure I know what you’re saying. You feel it’s perfectly fine if their encryption is done in such a way that they can read the encrypted information on the server as long as they don’t make a lot of money on it?
You are way off. For reference, here's what you asked
And my answer
Ahhh going way back to the start. Got it. Glad we’re on the same page now.
Well yeah, I just wanted to know first what you were asking before answering
Can we verify they are still using the Signal protocol?
Not realiably, afaik
If they are, they’ve probably modified it.
