(Edit, for context: the original submission title was “WhatsApp can now read your recent messages when you report a user”) By selecting a specific part of the article to highlight in the title, you introduce your own bias before people even begin reading.

> “WhatsApp beta for Android 2.20.206.3” Sorry but there is zero information in that title. I'm not going to use that. The intention of my post is to make more people aware of this new 'feature'. If some other user had posted this article with that title, I wouldn't have clicked it and I wouldn't have know of this new change.

I somehow don't think FB's world class engineers would fall for the cryptographic doom principle, so this would imply MAC-then-Encrypt-then-MAC, no? :D

This is not opt-in. You can either report or not report. There is no way to report but not send the messages. The reporting is opt in. The sending of messages tied to the reporting is not

There have been several unofficial reports of Facebook unifying the backend messaging among Instagram, WhatsApp and FB Messenger. If and when that happens, E2EE on WhatsApp will finally be completely gone. Anyone knows how far along (or canceled) that plan is?

As much as I like E2EE, I don't see where the problem lies? It's you who opts in into getting a third party involved. E2EE doesn't mean that no third party is ever going to see the content, it only means that nobody sees it by default .
