Anthropic is implementing stricter usage policies that effectively ban third-party integrations like OpenClaw from Claude starting April 4th. Under the new restrictions, users will no longer be able to use their standard Claude subscription limits when accessing the AI through alternative harnesses, forcing them to pay additional fees for the same service. This move signals a broader industry trend of AI companies exerting tighter control over their platforms, potentially fragmenting the ecosystem of AI tools that developers and users have built around major language models.
