I read it and don't understand. Why is this better than Signal? Or the 500 other secure file/messaging protocols?

Jabber seemed to work perfectly for Snowden...

Because analysing network traffic wouldn't allow an adversary to see what you're sending with Signal, but they could still tell you're sendig a secure message.

What the Guardian is doing is hiding that secure chat traffic inside the Guardian app, so packet sniffing would only show you're accessing news.

I downloaded the guardian app and couldn't find the option.

For one, ease of access. Say you’re trying to break a story, who are you going to message with signal? Because you’re going to need to get that contact info somehow right?

Snowden is permanently stranded in Russia. That’s not exactly a great example of an anonymous source.

...The Guardian?

Use your browser? These are strange questions.

Did you notice that I used the past tense?

Messaging protocols already resemble the frameworks that come out from time to time. And their effectiveness is due to the fact that they require a certain quota of users.

It's just a secure messaging app with a direct line to Guardian journalists. How to use 911 or special numbers when you're not feeling well.
