“But the flip side of that was lock-in. Unlike Android phones—which are typically designed to allow users to make use of alternative app stores and even install different operating systems—iPhones use software and hardware locks to prevent users from modifying Apple’s rules. This is a system that works well, but fails badly. So long as Apple remains a benevolent dictator, your iPhone is a walled garden that protects you from the bad guys who want to attack you. But if Apple turns on you, that walled garden becomes a prison, one that pens you in and makes you easy pickings.”
