Websites Gatekeep AI Agents

Major websites are beginning to block, require licensing for, or selectively permit AI assistants to act on users' behalf. Companies cite security, policy violations, or data‑licensing models while others form exclusive partnerships to allow agent access, producing a patchwork of allowed and blocked agent behaviors. — This changes how useful consumer AI agents can be, concentrates bargaining power with large platforms, and raises questions about competition, security, and consumer choice.
