The Fruity Cargo Cult Apple has appointed itself internet policeman and is censoring advertising companies from its devices while refusing to explain precisely who gets banned or why.
According to AdExchanger. Job’s Mob has expanded its WebKit tracking restrictions in iOS 27, reportedly creating a list of hundreds of advertising technology companies that could be prevented from collecting data or serving advertisements. The move gives Apple enormous power over businesses that depend on reaching customers through Safari and other browsers running on its devices.
The original crackdown affected companies including The Trade Desk, LiveRamp, ID5, Permutive and Audigent. Apple’s restrictions went beyond preventing tracking; The Trade Desk discovered that its principal advertising delivery domain, adsrvr.org, had been blocked, effectively preventing it from serving ads to Safari users running the latest operating system.
The blacklist has reportedly grown into a much larger collection of advertising platforms, customer data businesses and identity providers. Two sources familiar with the changes told AdExchanger that the list is maintained in a private GitHub repository, leaving affected companies with little information about how Apple decides who deserves the corporate death sentence.
Worse still, Apple has introduced a system that lets it update its blocking rules remotely. Previously, adding or removing companies required an operating system update, but the new arrangement means Job’s Mob can effectively pull the plug whenever it chooses, potentially without the affected business even realising what has happened.
The technology relies on WebKit, the browser engine used by Safari and other browsers on iPhones. Apple’s blocking rules include checks for known cross-site trackers and fingerprinting techniques, although their application appears capable of catching legitimate advertising delivery systems alongside tracking operations.
The arrangement has a particularly unpleasant smell because Apple operates its own growing advertising business. Job’s Mob can interfere with rival advertising infrastructure while flogging advertising through its own platforms, raising questions about whether its enthusiasm for privacy might occasionally coincide with its enthusiasm for making money.
AdExchanger reported that The Trade Desk had identified an example in which its advertising bids were blocked on Safari while Google’s bids continued to work. The publication was still investigating whether Google’s DoubleClick infrastructure appeared on the expanded list, leaving questions about how consistently Apple’s restrictions are being applied.
The consequences extend beyond advertising companies because independent websites rely on advertising revenue to support free content. If Apple’s restrictions make those advertisements less valuable, publishers could lose income while advertisers redirect spending towards enormous platforms with their own customer data, including Apple’s increasingly lucrative ecosystem.
Apple has long presented its privacy policies as a defence against intrusive tracking, and there are legitimate reasons to restrict companies that follow users across websites without meaningful consent. The problem arises when a company controlling a major computing platform decides privately which businesses may operate, with little transparency or independent oversight.
The controversy has prompted criticism from the advertising industry, including IAB Tech Lab chief executive Anthony Katsur, who argues that governments should establish and enforce internet privacy rules. That position carries its own difficulties, given the industry’s poor record on tracking, but it raises an uncomfortable question about allowing an enormously powerful technology company to act as judge, jury and executioner over its commercial rivals.
Apple has yet to publish a comprehensive explanation of its expanded blocking system or provide a clear public appeals process for affected companies. Meanwhile, its engineers can continue adjusting the restrictions remotely, leaving hundreds of advertising businesses wondering whether their access to millions of potential customers depends on the next decision made inside Cupertino.
