We won’t do any interoperating if it doesn’t uphold our rigorous privacy bar and that means message contents are encrypted with the protocol and metadata is encrypted using the techniques that we use to keep it private.

And then how do we trust that once we’re interoperating that our privacy promises are being adhered to on the backend of the other side? These are not questions with clear answers at the moment.
