Anti-debugging (and even anti-anti-anti-debugging) tricks have been commonplace on the DOS/Windows side of things for a long time. Any old cracking/unpacking information will discuss those in varying amounts of detail. How easy it is for the user to have control over what apps do is inversely related to how user-hostile the platform is.
