Safari 12.1, Shipping in Next MacOS and iOS Updates, Drops Support for Do Not Track Preference ⇥ developer.apple.com

Contrary to public perception, Do Not Track has always been entirely voluntary for websites. Web properties were given the chance to respect the preferences of users who proactively stated that they did not wish to be tracked. Not only did they ignore this preferences, they cynically exploited it to more accurately fingerprint individual users. This is why features like Intelligent Tracking Prevention and content blockers are so critical; they are tools for users to gain back control over the web that they have been forced to cede.
