Mac apps have been able to “see” the entire display ever since the Mac debuted. The Mac needs … the power for apps to shoot the user in the foot.
An example from the sandbox debate (also quoted by Gruber):
“Cocoa-based Mac apps are rapidly being eaten by web apps and Electron psuedo-desktop apps. For Mac apps to survive, they must capitalize on their strengths: superior performance, better system integration, better dev experience, more features, and higher general quality.
But the app sandbox strikes at all of those. In return it offers security inferior to a web app, as this post illustrates.”
