This [...is less profitable, thus removing incentive] is probably true, unfortunately. I personally seriously considered this space and actually wrote a quite complete prototype with this exact goal more than a year ago, but eventually decided to not move forward with it at the time. One problem is that it is really hard for an average user to distinguish BS security claims from proper crypto. An average user would likely consider Snapchat to be more secure than an E2E app.

Mulling on this a bit more - the profitability is further impacted from the inability to mine customer data on a secure app. Anecdotally, when presented with a free unsecure app vice a paid secure app, average Joe will go with the free app. Maybe there isn't a true demand like eps mentions
