Example: I don’t want someone to screenshot my Snapchat message but I don’t want my bank to prevent me from screenshotting the app because of “security” (aka security theater).
I don’t know how you make those two concepts work together.
One random thought that I just had is that when an app uses DRM it just show a black screen when you screenshot. I wonder if could implement that for things like Snapchat to get the same protections.
