Apple provides a framework that allows advertisers to target Apple users and end-users with advertisements. While many people prefer that when they see advertising it is relevant to them and their interests, the detailed information that is data mining collected, correlated, and available to advertisers in repositories is often disconcerting. This information is valuable to both advertisers and attackers and has been used with other metadata to reveal users' identities. Organizations should manage advertising settings on computers rather than allow users to configure the settings.
