A report published October 2, 2026, said Apple had replaced an initial set of WebKit ad-tech blocks with a remotely updated pool of hundreds of companies that could be excluded. The report attributed the account to two people with direct knowledge of WebKit updates.
The reported pool spans ad-tech and data firms
The report described potential entries across customer-data platforms, ad- and marketing-technology companies, data sellers, and identity-graph operators. It also referred to data-management platforms and demand-side platforms.
The list could be updated remotely
The same report said Apple devices regularly consult the remote list, allowing its contents to change without a new iOS release.
Five providers were reported as still blocked
The report said The Trade Desk, LiveRamp, ID5, Permutive, and Audigent remained blocked on Apple devices running iOS 27.
WebKit code adds tracking-prevention rules
A WebKit commit adds code to manage and apply a tracking-prevention content-rule list. In plain terms, the code handles a set of rules intended to prevent tracking.
