Publishers Battle Google; MPs Push for Social Media Age Ban
Digest covers five US publishers suing Google over alleged ad tech manipulation; Google appeals a landmark antitrust ruling on its search monopoly; and more than 60 Labour MPs urge Prime Minister Keir Starmer to back a ban on under-16s using social media. It also notes Threads surpassing X in daily mobile users, per Similarweb. The publishers—Penske Media, Advance Publications, Vox Media, McClatchy, and The Atlantic—accuse Google of abusing dominance over ad servers and exchanges to stifle competition, including allegedly seeing competitors' bids before submitting its own and underpaying publishers (The Atlantic claims revenue reductions of over 40%). Google has appealed the August 2024 ruling, arguing the decision overlooked competition and rapid technological change. In the UK, the letter coordinated by Plymouth Moor View MP Fred Thomas asks Starmer to mirror Australia’s age restrictions; culture secretary Lisa Nandy and others warn of potential drawbacks. Threads’ mobile growth is highlighted with 141.5 million daily active users versus X’s 125 million.

Google Antitrust Ruling Spares Ad Stack, Pressures Trade Desk
A federal judge ruled that Google must open up its ad exchange and publisher ad server to more competition but stopped short of forcing a breakup of its adtech stack. The remedies include connecting AdX and DFP to Prebid, requiring equal terms for AdX bids on alternative servers, curbing self-preferencing, and sharing auction data. For The Trade Desk, which has positioned itself as the neutral alternative to Google's walled gardens, this outcome weakens its core pitch: a fairer and more transparent auction reduces the urgency for publishers to seek alternatives like OpenPath. The article also notes that Google's decision to keep third-party cookies has already slowed adoption of alternative IDs like UID2.0. Analysts suggest The Trade Desk's narrative is shifting towards CTV and agentic advertising as the open-web competition with Google evolves.
