Whatsapp CANNOT read messages when e2ee is enabled, this client-side snooping was discussed when the protocol was first implemented. Whatsapp collects a ton of metadata and social graph info, but not message content.
Well you type messages in in plain text and they decrypt it to show you the messages at the other end. So they can do the nefarious processing on the client side and send back results to the mother ship. E2EE is only good when you trust the two ends, but with WhatsApp and Messenger you shouldn’t trust the ends.
Sure, but any messaging app (including Signal) could have these backdoors in place. Heck, there’s even vectors for unrelated apps on your phone to read this data once unencrypted.
That’s actually true. We don’t know the real-time server code of Signal. Though other apps cannot read what’s written inside Signal, that’s the good part. I prefer private server + Matrix but Signal is the easiest for regular people.
Would this mean I could finally ditch what’s app and use only Signal?
No, Signal announced they won’t implement interoperable messaging.
kind of dumb they could get huge market share
Yeah, this worked so well for XMPP when everybody federated with Gmail chat.
Well, it worked out for Google when it federated with Jabber, who first open sourced XMPP.
It’s not. There is no privacy if you send your message to Whatsapp servers.

Would it not be E2EE? Isn’t that one of the reasons for using the Signal protocol?
Yes, the “delivering” part would be E2EE. Do we really know the afterwards if they can read their users’ messages? They probably can.

Signal clients are open-source.
Signal is only officially distributed through Google Play, so their APK isn’t reproducible, and I believe it still contains binary blobs.

if i remember correctly, it would be E2EE (WhatsApp and Messenger are too) but Meta stores the encrypted message on their server
Signal does not care about “market share”, they’re a non-profit.
Not if signal doesn’t want to support WhatsApp, and I don’t think they’re going to unfortunately :(
