Unless they radically change how Facebook messenger works I don't see how it could even be called end-to-end encryption. For it to work how it does now (online and independently through the app) they would have to hold the encryption keys.

They would have to instead tie Facebook messenger to a phone like Whatsapp does and use a web app to send messages directly from the device instead. I don't see how else it could be done and still be called end-to-end encryption.

> Unless they radically change

And according to the article, this radical change is coming. Why is that so hard to believe?

Because there are no details beyond vague promises, and it entails serious restructuring and UX trade-offs that may affect revenue. At the moment, skepticism makes much more sense.
Just to be clear, do you think that the NYT is mistaken, or that Facebook has committed to something that is too difficult to execute due to technical and revenue concerns?
I don't think they committed to anything. It's just vague promises that can be reinterpreted in many ways, most of which can compromise trustworthy e2e encryption while also implementing some form of loophole-ridden e2e encryption.

Yeah, WhatsApp is e2e encrypted by default, but it also automatically backs up all your chat history encrypted using a WhatsApp-owned private key. Sure, you can opt-out of backups, but will your peers do as well? Without a clear spec, I think it's perfectly reasonable to be very skeptical of what will be the final product of this operation.

> just vague promises

Now I know you didn't read the article. There were no promises made because this was based on conversations with employees, not a press release.
