This is something I'm worried about a well. Let's say someone has written a semi-successful password keeper app and makes $200,000 per year with it. One day he realizes that there are secrets stored by the users of his app that are worth millions or perhaps even tens of millions or more. Just how much trust can you put into an app? Even if it is open source - there may be a rogue update. Either because the app developer was hacked or because he claims to have been hacked. It's scary.
