Anthropic has begun enforcing stricter monetization controls around Claude, effectively pricing out users of third-party interfaces like OpenClaw starting April 4th. The move represents a shift toward protecting subscription revenue streams as AI companies face mounting pressure to demonstrate business viability. Users previously could apply their Claude subscription credits to OpenClaw's interface; under the new policy, they'll need to pay separately for third-party access. This reflects a broader trend among major AI labs to consolidate their business models and reduce friction for developers using their official products.
