AppLovin Sues Unity Over Data Collection in Ad Quality SDK
AppLovin has filed for a temporary restraining order against Unity in the Superior Court of California, San Francisco, alleging that Unity's Ad Quality SDK improperly collects data from AppLovin's advertising auctions and uses it to train models that compete against AppLovin. The dispute is also heading to JAMS arbitration. AppLovin seeks to prohibit Unity from collecting its 'Protected Data,' which includes ad creatives, user and device info, impression revenue, and auction identifiers. Unity disputes the claims, stating that Ad Quality is a small free product designed to prevent harmful ads and that AppLovin is using litigation to stifle competition. The parties attempted to resolve the matter before filing, but AppLovin rejected Unity's proposed wind-down of Ad Quality's MAX-related collection, citing unresolved issues with previously collected data and other mediation platforms. A hearing is scheduled for September 30.
This legal dispute between two major mobile advertising platforms could reshape data collection practices in the industry, affecting how SDKs handle competitive data and potentially impacting ad targeting and measurement.

At its DevDay, OpenAI introduced several major innovations, including 'dots', persistent AI agents that can be linked to over 4,000 apps and work 24/7. These agents are powered by GPT-6 Astra and are seen as a direct response to Meta's Muse. OpenAI also unveiled a new model, GPT-6.1 Sol, which offers Astra-level intelligence at one-fifth of the cost, and GPT-6 Astra Ultrafast, the fastest frontier model, available via a new $500 Pro tier. Other announcements included 'Space', a collaboration workspace with interactive 'Living Pages', and Codex in the Cloud for remote access. The company also launched a plugin platform and an OpenAI Marketplace, with partners like Figma, Adobe, HubSpot, and Salesforce. Amidst these releases, OpenAI and other tech leaders signed a White House accord on Super Intelligence safety, following a delayed model launch due to safety concerns.
AI agents threaten advertising as we know it
AI agents like Meta's Muse, OpenAI's ChatGPT, and Google's Gemini are disrupting traditional advertising by not clicking banners or sponsored results, threatening the core revenue of platforms like Meta and Amazon. New monetization models include subscriptions, transaction fees, and pay-for-results. Protocols such as Google's Universal Commerce Protocol, OpenAI/Stripe's Agentic Commerce Protocol, Visa's Trusted Agent Protocol, and Ad Context Protocol standardize agent-commerce interactions, creating new ad slots within agent workflows. Early signals include Amazon blocking Muse and declining Google traffic to news sites. Despite the threat, ad giants report growth, including ChatGPT ads reaching $1 billion annualized revenue, proving ads work in AI assistants, especially at the top of the funnel. Adoption remains early, with only 5% of US consumers using agents for fully autonomous purchases.
