Cloudflare Opens AI-Training Block Setting to All Customers

The significance lies less in the opt-out itself than in Cloudflare's attempt to split search indexing from AI training, and in its role as an arbiter of which crawlers count as responsible. That certification power affects AI developers and site owners alike, since compliance now carries reputational weight. The gap between the share of sites blocking training and the far smaller share blocking search crawlers suggests site owners still treat visibility and training as separate concerns. Whether that gap narrows, and whether certification becomes a real constraint or a label, is the open question.
