> Are you in the right thread? The discussion here is about what information Google can get from GCM messages

The parent poster of the post you initially replied to asserted that Signal was "giving NSA the only thing what they want: metadata from Google", so I guess that's where tptacek is coming from.

On a side note, Google can't actually know the message sizes because GCM is used without a payload.

Yes, but they're right: we started talking past each other several comments ago. Sorry!

If tptacek wanted to reply to the NSA comment, that's fine, but that's not what happened.

Your side note also applies to that comment, but not mine, so I think it belongs there, not here.
