Good for protecting the message itself, but it does nothing for metadata. These days the metadata is what kills you. (Who talks to whom, when, and how often reveals enough to press the drone missile button, apparently.)

OpenPGP + SMTP as a starting point as email can reach many and Thunderbird makes OpenPGP happy clicky simple. The body includes instructions for the E2EE chat servers to use. Metadata trail ends there. Other circles of friends are joined in by other means. E2EE ejabberd (OTR+PGP+OMEMO) servers switched up after everyone is on the first outer layer of chat servers. Old servers are wiped. Of course all of this assumes nobody is silly enough to use a cell phone or all of this is futile. Everyone is using a laptop they paid cash for and a clean install of a generic minimal install of Linux and Coreboot running a script to make everything ephemeral and the OS nearly immutable. No security distros as they have all been infiltrated, just a vanilla simple Linux and a script.
