Why You'll Never Know If Your Data Trained an AI
The article explains that despite the EU AI Act's requirement for general-purpose AI providers to publish summaries of their training data, individual creators will rarely find out whether their specific content was used. An EU Commission FAQ on the Article 53 template reveals significant limits: providers only need to list the top 10% of domains by data volume (or top 5%/1,000 for SMEs), while individual works, URLs and smaller datasets are excluded. Existing models have until August next year to comply, with penalties of up to 3% of global turnover. The article contrasts this with a non-binding Japanese government code that requires providers to answer rights-holder queries about specific websites. It also details opt-out options at Meta (Facebook/Instagram) and LinkedIn, while noting opt-outs only affect future training, not already trained models. Indirect methods such as memorisation tests or US copyright discovery remain the only ways to verify inclusion.
The EU Commission's FAQ clarifies the practical limits of AI Act training-data transparency, affecting AI model providers, publishers, and rights holders across the EU, though it does not fundamentally alter the adtech landscape.

Céline Flores Willers urges B2B marketers to think like B2C
At DMEXCO 2026, Céline Flores Willers, founder of The People Branding Company, argued that B2B marketing often appears outdated due to fear of innovation (FOMU). She demonstrated creative tactics like using a robot sidekick 'Robi' and branded T-shirts to boost attention and branding. She highlighted LinkedIn as the central platform for B2B, citing a SAP Taulia case where employee-generated content, boosted via Thought Leader Ads, achieved 2.3x higher engagement and 70% higher click-through rates with a small budget. Willers also cited examples like Legora's campaign with Jude Law and Merz Lifecare's 25-post merger documentation as successful 'building in public' strategies. She concluded by urging B2B marketers to be more creative and learn from B2C approaches.
LinkedIn says don't treat leads as finish in B2B
At LinkedIn's B2Believe event in its new Empire State Building space, executives and practitioners called for a shift from lead-centric B2B marketing to a 'full journey' approach that links signals, targeting, creative, full journey, and measurement. Jae Oh, senior director of product management, revealed that fewer than 10% of upper-funnel audiences make it into bottom-funnel campaigns, urging marketers to connect awareness with demand capture. Research from LinkedIn's B2B Institute with eMarketer showed 77% of marketers say they no longer target individuals, yet only 31% have a playbook for activating audiences down the funnel. Practitioners from Canva, SAP, Mastercard, and others shared examples of aligning marketing and sales on common signals. LinkedIn also outlined a product roadmap focused on cost-per-opportunity targeting, multi-format campaigns, agentic workflows, and incrementality forecasting.
Nadella's AI Pivot: Can He Reinvent Microsoft Again?
This article examines CEO Satya Nadella's efforts to transform Microsoft for the AI era. Despite a near $4 trillion market cap and early investment in OpenAI, Microsoft trails rivals like Nvidia, Anthropic, and Meta in key AI segments. The company is shifting from subscription-based pricing to consumption-based billing (UBB) for its AI products, starting with Copilot Cowork. GitHub Copilot has seen growth to 50 million users, but Microsoft lost its exclusive cloud relationship with OpenAI. Nadella promotes building a 'frontier ecosystem' rather than a single frontier model, integrating various AI models into Copilot. Challenges include sluggish Copilot adoption, competition from AI-native startups, and uncertainty among enterprise customers about usage-based costs.
