It's a choice that Google made to obfuscate their DRM by calling it "FLAG_SECURE", at the cost of usability and security for everyone else. Just check out this delightful doublespeak: https://developer.android.com/security/fraud-prevention/acti...

> When a window is flagged with FLAG_SECURE, Android prevents screenshots from being taken and prevents the window from being displayed on a non-secure display, such as a TV or projector. This helps to protect the information that is being displayed in the window from being accessed by unauthorized people.

What's a "secure display"? Why, none other than our old friend HDCP: https://source.android.com/docs/compatibility/16/android-16-...

So the docs might imply that "the information" is your banking information, and the "unauthorized people" are, I guess, dudes with binoculars outside your window. But actually "the information" is Netflix and the "unauthorized people" are you.

That's why you can project your OTP codes on a 50-foot wall as long as your projector is HDCP-compliant.
