Anthropic says it sharply curbed distillation attacks on Claude, drawing hypocrisy criticism

Anthropic announced it has made significant progress in reducing the effectiveness of distillation attacks against Claude, publishing a technical explainer.

The move drew accusations of double standards: critics argue the company built a business on humanity's collective knowledge—training on millions of books while discarding the physical copies—yet now objects when others learn from its output to build competitors. As one critic put it, the knowledge never belonged to Anthropic, and training a model on it doesn't make it theirs.

The episode highlights the industry's sharpening tension over distillation defenses and training-data ownership: labs rely on open knowledge to train, then seek to monopolize reuse of their models' outputs.
