I mostly agree with you, but disagree that snapchat is about deletion of data. They may delete the content of the data, but who you interact with, when, and when those messages are retrieved, may have some value. The idea that you are sending messages that can't be retrieved when compared to messages that are kept, may have some value as well, but likely only if you have the ability to compare these 'secret messages' to 'non-secret messages'.
