RCS Messaging Encryption With the launch of Google's RCS messaging protocol, is there any reason as to why it doesn't support end-to-end encryption, or is it a feature that they intend to implement at a later time?

RCS improves the old SMS by bringing modern features. It provides client to server side encryption but not provide end to end encryption.
According to What is RCS messaging? Everything you need to know about the SMS successor:


  But Chat is missing one critical element: While the original RCS protocol allowed the implementation of client-to-server encryption, Chat does not offer end-to-end encryption like iMessage or Signal. Rather, it retains the same legal intercept standards as its SMS predecessor.


Asked about the privacy issues related to RCS, Google's product management director for Android Messages replied:


  We fundamentally believe that communication, especially messaging, is highly personal and users have a right to privacy for their communications. And we’re fully committed to finding a solution for our users.


Google is working on it but no indication is given as to when end to end encryption will become a feature. In the meantime, when sending a message,


  It's encrypted in transit, but it’s not fully end-to-end encrypted, so your RCS provider can potentially see the contents of your messages, and turn them over to the government if properly asked. Google says it will delete them from its servers as soon as they’re delivered to your phone


Like for SMSes, the providers will be able to read your messages until Google decides to implement end to end encryption.
