Amazon Bars Meta’s Muse AI From Shopping on Its Site
Amazon has cut Meta’s twelve-day-old Muse agent off from shopping on Amazon.com, serving users a popup that cites its Conditions of Use rather than accusing anyone of hacking.

This article covers Amazon’s stated objections, how Muse actually reaches a site with no agent API, the litigation timeline, the $68 billion advertising business at stake, and how Amazon’s own Buy for Me feature differs.
