What we talk about when we talk about interoperable end-to-end encryption
I was wrong about Snapchat, but I was also kinda right.
When I first encountered the idea of disappearing messages, I was both skeptical and alarmed.
Skeptical because disappearing messages have an obvious defect as a security measure: If I send you a message (or a photo) that I don’t want you to have, I lose. You can remember the contents of the message, or take a screenshot, or use a separate device to photograph your screen. If I don’t trust you with some information, I shouldn’t send you that information.
