Indeed, it should be clear to everybody that a motivated actor could record the view-once message, if nothing else by taking a picture of the screen with another device.
They are still useful to convey (in a rather strong way) the intention of keeping the message off-the-record, and to avoid the risk of a third party reading it e.g. by stealing the phone.
Yea, view-once features in apps are mostly an illusion that’s oversold.
We have something close to some sort of an actual view once thing at work… it involves controlled access into secure rooms with no windows, lawyers, NDAs, security takes your phone and whatnot kinda deal.
A self destructing message is better than nothing, but hardly a guarantee
