# Anthropic's Watermarking Move: Ben Thompson Critique of EU AI Act Compliance

> Anthropic recently decided to embed machine-readable watermarks in every Claude output worldwide, not just in Europe, in order to satisfy the EU AI Act's new transparency rules. In this Stratechery piece, Ben Thompson argues the decision is a bigger deal than it looks and, in his word, terrible in its implications. His critique is less about the technology than the precedent. By applying an EU rule globally rather than carving out a compliant European version, Anthropic effectively lets Brussels set a default for users everywhere, a dynamic sometimes called the Brussels effect. Thompson also probes the deeper tension between a lab's stated product philosophy and the compromises that regulation forces, asking what it means to permanently mark all AI writing as artificial. The essay is a good companion to the day's news that the AI Act's transparency obligations are now live with real penalties attached. It captures the awkward reality that the rules shaping how AI behaves for the whole world are increasingly being written in one region, and quietly exported to the rest.
