There is nothing secure about sending encrypted content to notifications. If it were secure, it would only notify that there is a message, with no details included.

You're right. This is configurable via settings, but is not the default state.

That said: if I can get friends and family to use Signal instead of iMessage, that gives me the opportunity to disable those notifications and experience more security benefits.

But I agree with your point: most people think that Signal is bulletproof out of the box, and it's clearly not.

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.
