Optimixed Overview
Optimixed's original report on this story.
Apple has begun blocking ad-tech companies that track users for targeted advertising inside Safari, forcing publishers to reconsider their revenue strategies. As reported by Digiday, the blocklist already affects major players and threatens broader disruption across the ad-tech ecosystem, with publishers reporting reduced bidding on their traffic. In response, many are reviving plans to implement IAB Tech Lab's Trusted Server infrastructure, which moves ad transactions off users' devices onto publisher-controlled servers that Apple cannot directly intercept.
