Apple Safari Blocklist Pushes Publishers to Trusted Server
Apple's latest software update has started blocking ad tech companies that track users for targeted advertising in Safari, prompting publishers to urgently revisit IAB Tech Lab's Trusted Server. This server-side solution moves ad auctions from users' devices to publisher-controlled servers, bypassing Apple's blocklist. Publishers like Paradium have already adopted it, while others are evaluating their options. The move highlights Apple's growing control over digital advertising, raising concerns about market power and the impact on publisher revenue. As Apple expands its own ad business, the blocklist underscores the shifting power dynamics in the ad tech ecosystem.
Apple's Safari blocklist is a significant policy shift affecting ad targeting and publisher revenue, forcing adoption of new infrastructure.

Apple iOS 27 Blocks The Trade Desk from Serving Safari Ads
Apple's iOS 27, released on September 14, has blocked major programmatic data firms—including The Trade Desk, LiveRamp, ID5, Permutive, and Audigent—from serving ads or collecting data in Safari via a WebKit blocklist. This blocklist, dynamically updated through a private GitHub repository and WebKit code, prevents ad delivery on iPhones, iPads, and macOS 27.0.1, affecting CDPs, DMPs, and DSPs. Unlike ATT, which only limited cross-app tracking, this fully blocks ad delivery. Google may be exempt, raising competitive neutrality concerns. Some vendors like LiveIntent, Lotame, and ConnectID remain unaffected, but the block underscores the power imbalance between walled gardens and the open web, reducing publisher demand and shifting market composition. It follows regulatory actions in France, Italy, Germany, and a UK class action over ATT's competitive implications, with Germany's Bundeskartellamt concluding in mid-2026 with Apple commitments. The impact is currently limited due to low iOS 27 adoption, but signals long-term challenges for identity-based advertising.
TSMC Q3 Revenue Up 51% to Record, Stock Falls
TSMC reported a 51% increase in third-quarter revenue to 1.49 trillion Taiwan dollars (EUR 41.7 billion), surpassing expectations. The semiconductor giant, a key supplier to Apple and Nvidia, continues to benefit from the AI boom and strong chip demand. However, the stock declined despite the record results. The company plans to invest EUR 52-56 billion in expanding its manufacturing facilities this year, including a joint venture with Sony for image sensors. TSMC's market capitalization is approximately USD 2.45 trillion, making it the most valuable company outside the US. The company's growth is also boosting Taiwan's economy, with exports rising over 70% in August and GDP expected to grow 11% in 2026.
Musician sentenced for AI streaming fraud
A 54-year-old musician in the US has been sentenced to 18 months in prison for orchestrating a large-scale streaming fraud scheme. Using up to 10,000 bots, thousands of fake accounts, and thousands of AI-generated songs, he manipulated streaming platforms such as Apple Music, Amazon Music, and YouTube between 2017 and 2024. The fraudulent streams generated millions in royalty payments. At one point, his songs achieved 80.9 million streams in April, far surpassing Taylor Swift's 9.3 million. The court also ordered him to repay over $8 million. His defense argued that no musicians were directly harmed, but prosecutors countered that real artists and fans were deprived of royalties.
