On September 22, 2026, Amazon blocked Meta's consumer AI agent MetaMuse from accessing any products on Amazon.com, saying Muse does not identify itself as an AI agent while browsing and citing a Sunday change to its conditions of use. The discussion widened from platform access to consumer trust after an ACI and YouGov survey found only 7% of fashion shoppers would trust agents to buy completely autonomously. It has now turned to agent behavior: a reporter used Muse to repeatedly hold RealReal cart items for 20 minutes at a time, locking products for hours. Whether other platforms wall off rival agents, and how sites guard against cart holds, remains open.
