Amazon Blocked One Agent. It Couldn't Block the Model.

The Perplexity/Amazon case just established that platform authorization and user delegation are distinct legal requirements. Every platform in the world now has to decide which agents they trust - and how. On March 9, a federal judge handed Amazon a preliminary injunction blocking Perplexity's Comet shopping agent from accessing Amazon's platform. Amazon must respond to Perplexity's appeal by April 22. The case is live. Most coverage focused on the competitive angle - Amazon protecting its ad revenue from an AI that bypasses sponsored listings. That's real.
