Since we don’t know how this chat log was collected, it’s hard to say how the security/privacy model failed. It could just be a failure in maintaining secure use by all participants. I don’t have any special knowledge about the best tools for this, but organizational structure is definitely part of the solution.
I did run across an interesting tool recently that could be useful: https://chitchatter.im/ https://github.com/jeremyckahn/chitchatter
Seems to check off a lot of boxes including self-hosting and memory-only chat logging which ensures ephemerality. The usability would obviously be more involved since it isn’t using ph#s and isn’t an app that’s as accessible to average non-tech folks.
I think having a tier comms structure is likely a good solution. Maybe use Signal for general info and organizing things that are not as sensitive, but only use ephemeral secure chats for higher tier comms between vetted leadership for
kinds of things. I don’t want to wag my finger at these folks trying to organize on the fly, but using mass chats for certain discussions is not recommended.
