Apple is under more legal pressure than ever for its apparent 'anti-competitive' practices. They have on many occasions pushed the line of user privacy and security to defend their business. Features like this benefit a small group of people, but help Apple enormously in defending itself from litigation.
Edit: Downvote? Why are companies given the benefit of the doubt as if they were human and caring when they are clearly not! Large listed tech companies like Apple will ALWAYS act in their own interest first. User privacy is the advantage Apple has over its competitors who rely on free services and advertising. It is in their OWN INTEREST to pursue this path which in turn impacts others ability to compete. Must we continue to be so grossly naive?
