Yes, I think that was the first event that pushed Google to focus much more on security. The second one was of course in the summer of Snowden, when Google found out NSA had <i>full access</i> to its network. Since then it has taken quite a few measures to improve security and now it treats its own network as the &quot;untrusted Internet&quot;.<p><a href="https:&#x2F;&#x2F;www.usenix.org&#x2F;conference&#x2F;lisa13&#x2F;enterprise-architecture-beyond-perimeter" rel="nofollow">https:&#x2F;&#x2F;www.usenix.org&#x2F;conference&#x2F;lisa13&#x2F;enterprise-architec...</a><p>Unfortunately, other than the default full disk encryption it&#x27;s pushing on Android 6+ devices, I&#x27;m not really seeing Google push client-side encryption anymore. I wonder if it even wants the E2E email extension to be fully developed anymore. And even though it should be quite trivial for Google to adopt Signal&#x27;s text and voice encryption in Hangouts, I doubt it has any intention of ever doing that.
