The whole app was a red flag from the start. Lets create a chat app where we can send timed photos and videos that self destruct. What could kids/creeps possibly use it for?
The alternative is pretty bad also. Let's create a chat app where people have the entire history of all the stupid things you said as a child and teenager for all time. I'm glad a grew up with ICQ and MSN messenger which were far more ephemeral histories mostly because nobody thought to save them.
