Thanks.

Worth reading the response from Matrix as well (https://matrix.org/blog/category/security).

My first reactions are to wonder how many of these issues are associated with federated (as opposed to fundamentally decentralized) group chat in general. Matrix seems to be taking the position that some of these issues ultimately relate to trust vs lack thereof in the homeserver as a bottleneck.

I also wondered if there was a good security model for federated or decentralized group chat at all at the moment. I can't remember offhand if Briar was adding groups or not, but that's not federated.
