Once again there is a trade off between security and user convenience.

If security is the main differentiator then app should start in the most secure mode possible. Then allow users to turn on features while alerting them to the risks. Or at least ask users at startup whether they want "high sec mode" or "convenient mode".

As the app becomes more popular as a general messaging replacement, there will be a push towards greater convenience and broad based appeal, undermining the original security marketing as observed here.
