My Android phone prevents me from recording phone calls at the request of my carrier, even though it's totally legal for me to do so in my jurisdiction.
I'm not loving where this is all going.
The most frustrating part about this "feature" is that you don't know it's enabled until the screenshot is taken and you're left with a picture of nothing.
That and some app authors thinking they're protecting you with this (referring to banking apps in particular)
The problem is that certain actions should only be acceptable if initiated by the user, physically. Think of the way Ctrl+Alt+Del works in Windows. This, of course, is not possible if you don't have enough fingers for the action, or something; here comes the loophole of assistive technologies, widely (ab)used for that on most platforms.
