> removing options for recipients to forward, copy, print, and download Oh please... Everybody can do a screenshot nowadays, and even Google itself integrated OCR into its Screenshot tool at Android a few years ago. What a waste of time to make the life of people harder who must use this "security" feature!
Yes, this system does not seem to prevent the information from spreading. I guess that the logic is that most people who know how to make a screenshot also know how to make a fake screenshot. So, let's say that Mr A is not a very honest guy. Moreover, Mr A has a sensitive document that could be a liability in court. He wants to share it with Mr B. But, he does not completely trust Mr B. With this system, he can share…
A would be better off using something like Snapchat for the confidentiality.
