There will always be data thieves. The real criminals are the lazy developers that make apps without full client side encryption. This would claim to make that obvious. If you put together an app that professes to send messages that are private to one other user, when in fact they are visible to anyone with access to your servers, you have sold your users down the river just because you are not a competent developer. This is widespread right now, but it doesn't mean it isn't true. However, as other people have pointed out, this particular idea looks like BS. Even so, I think it will be implemented in some form in a few years. It's time to end the "fingers in the ears, la la la" approach to data security that your post exemplifies.
