Tell HN: iPhone mirroring on iOS/macOS breaks screenshot protection on all apps

I appreciate that this is somewhat obvious on reflection, but I am surprised that no one is talking about it given that it breaks security/privacy flows for major apps (obviously a photo of the screen was always a risk)
This is always a very interesting topic for me. On one hand, I would like apps to be able to enforce rules like “no screenshots” or at a minimum “screenshot detection”. On the other hand, I want my phone to do what I ask you to do and not be forced to follow arbitrary rules.
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.
