Note that that report explains that the Double Ratchet E2E algorithm is used in Matrix, in large part because of the Open Whisper Systems implementation in Signal and subsequent licensing. So we're looking at an apples-to-apples comparison, at least with respect to this one piece.

Yes, it seems like a good choice of algorithm. And it seems like the implementation is also decent - they looked at that as well. It's a useful report and kudos to Open Technology Fund for funding it and to Matrix for making it public!

Still, this is only one piece of the overall security of Riot, so I'm still interested in knowing if there's any work going on looking at the bigger picture.
