Apple's iOS 27 Update Blocks Adtech Domains, Disrupting Web Advertising
Apple’s iOS 27 update has disrupted the digital advertising industry by blocking specific adtech domains within its WebKit engine, affecting Safari and other browsers on iPhone and iPad. This move prevents companies like The Trade Desk, ID5, LiveRamp, Permutive, and Audigent from serving ads or using alternative identifiers to track users. While Apple has partially addressed the issue for The Trade Desk in a beta release, the broader block on identity providers remains, with no clear timeline for a full fix. The update has raised concerns about Apple's opaque and potentially aggressive approach to privacy, which some argue undermines the open web and benefits Apple's own ad business.
