In snapchat, you're sending messages to friends, or at the very least individuals, who you trust have not rooted their phone to log messages.

Anything put to the public internet is there forever because antisocial corporations and the few individuals who do not respect privacy can operate at scale.

Asking a normal person nicely to delete something almost always works though, especially if not deleting it is a hassle

This is a series of assertions, which I assume are backed by your own intuition, but they are neither arguments nor observations.

Maybe we just have a very different threat model?

Snapchat style messages completely solves:

- someone you trust now later becomes untrustworthy and would use old messages against you

- messages are stored on your phone and can be found by someone else later

neither of these can happen if deleting messages is not an expected and normal part of the protocol

it does not solve the problem of sending messages to someone who already wants to hurt you (ie. the public internet)
