No, wait, there's a bug in this reasoning. Encryption is still very
necessary to preserve user privacy, i.e. to let an ALTO server provide a
user with information the user themselves may consider confidential
(e.g. their own uplink/downlink capacity). But of course if the user is
willing to redistribute even such potentially-confidential information,
there is no means for the server to prevent that.
