In the release notes for Safari 12.1, the new version of Apple’s browser installed in iOS 12.2, Apple says that it is removing support for the “Do Not Track” feature, which is now outdated. From a news writeup: “Removed support for the expired Do Not Track standard to prevent potential use as a fingerprinting variable,” the release note reads. The same feature was also removed from Safari Technology Preview today, Apple’s experimental macOS browser, and it is not present in the macOS 10.14.4 betas. According to Apple, Do Not Track is “expired” and support is being eliminated to prevent its use as, ironically, a fingerprinting variable for tracking purposes. It is entirely up to the advertising companies to comply with the “Do Not Track” messaging, and it has no actual function beyond broadcasting a user preference.
