Apple's iOS 27 update has quietly blocked hundreds of programmatic data companies from collecting data or serving ads on Safari, signaling a far-reaching shift in the company's privacy mandate. This move, which affects a dynamic list of companies stored in a private GitHub repository, could have significant implications for the ad tech and data management landscape, potentially leading to broader category-wide bans on CDPs, DMPs, DSPs, and other three-letter acronyms.
What AdExchanger reported
- Apple's iOS 27 update blocks hundreds of programmatic data companies from collecting data or serving ads on Safari
- The list of blocked companies is now dynamic and stored in a private GitHub repo, accessible only to Apple engineers
- Apple's new blocking process relies on a remote list that can be updated on the fly, without requiring a new iOS version
- The original list of blocked companies (TTD, LiveRamp, ID5, etc.) remains blocked, but the new list suggests broader category-wide bans
