In their defense, when the SnapChat founders were on Colbert awhile back, they were emphatic about saying, "There are many ways it can be saved!" And, were warning users that it's just a convenient thing, not any true protection.<p>But, yes, users can be easily confused, and they (intentionally?) got more downloads / users because people mistakenly believed that the images were 100% deleted.<p>For the HN/Techie audience, we of course never believe anything digitally transmitted to a recipient can be 100% deleted by the sender. Nothing will ever prevent brute force things like "having a camera over my shoulder, recording my screens".
