Snapchat owes its rapid ascension to the top of the social app pyramid to its disappearing messages, but the service has been transitioning away from ephemeral messaging in recent months. Not only can users pay to view messages more times instead of having them disappear forever, the company recently updated its terms of service so that it can save every single message you send, edit them however it wants, and publish them whenever it wants, all without having to ask for your permission or paying you any royalties.
