Apple Faces £2bn Claim from UK App Developers over ATT
Apple faces a £2bn collective action in the UK Competition Appeal Tribunal, filed by ATT Collective Action Limited on behalf of thousands of UK app developers. The claim alleges that Apple's App Tracking Transparency (ATT) framework, introduced in April 2021, imposed stricter consent requirements on third-party apps than on its own services, unfairly reducing developers' ad revenues and increasing user acquisition costs. The suit seeks compensation for losses between 2020 and 2025, during which Apple's advertising business reportedly grew from $1.5bn to $7.4bn. Led by Ann Pope, former CMA antitrust director, the case follows regulatory pressure across Europe, including fines from France and Italy and a German settlement requiring changes to ATT prompts. The CMA is also separately investigating ATT.
Major regulatory and legal challenge to Apple's ATT policy, which directly impacts ad revenue and tracking capabilities for app developers across the UK, a key market.

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.
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.
Microsoft Unveils Hybrid Intelligence, Open-Weight AI, RTX Hardware
Microsoft is repositioning Windows as a platform for 'hybrid intelligence,' enabling AI agents to run locally on PCs or in the cloud. The company announced the general availability of Microsoft Execution Containers (MXC), which sandbox agent execution and control access to files and networks, with support from Codex, GitHub Copilot, OpenClaw, and others. New AI models, including Microsoft's MAI Code 1.1 Flash, Nvidia's Nemotron, and DeepSeek V4 Flash, will run locally on RTX Spark devices, including the Surface Laptop Ultra (available for pre-order at $2,599). Copilot is gaining access to local files and system actions on Copilot+ PCs, rolling out in the coming months. Microsoft is diversifying its AI partnerships beyond OpenAI, building its own models, and aiming to regain trust after past missteps by emphasizing security and on-device processing.
