What about desktop apps? Every Win32 app has permissions to view and edit all the user's files and data, arbitrarily snoop on and hook into other processes running as the user, etc. The situation on Mac and Linux for most users is similar, except for sandboxed Mac App Store apps. On Windows there is a modern app model (UWP) that provides for app isolation and more granular permissions but the push to get software moved over to it seems to have stalled.
