Anthropic tightens rules on Claude use after third‑party “proxy” tools spark surge in token consumption

What happened

It has been reported that Anthropic sent an email last night telling users that paid subscriptions such as Claude Pro will from now on be restricted to Anthropic’s own products. The move provoked an immediate backlash from subscribers and developers who say workflows built around third‑party tools—most notably OpenClaw—were abruptly disrupted. Claude Code lead Boris Cherny reportedly engaged with users online to explain the decision, saying the subscription model was not designed to support continuous, automated consumption driven by external proxies.

The technical and commercial friction

Anthropic has blocked efforts to “spoof” the official Claude Code client and limited OAuth tokens so they work only with official Claude.ai and Claude Code clients; it has been reported that a number of developer accounts were suddenly suspended. The company frames the change as a response to abnormal proxy traffic that can produce fraud risk, permission abuse and runaway quota burn. Users counter that the platform is protecting margins: why else cut off heavy users mid‑stream without a transition window? Reportedly, OpenClaw’s founder has since joined OpenAI—adding fuel to the claim that the closure was always likely.

Wider implications and context

This is part of a broader tightening across the industry. Google and other vendors have been restricting quotas and tokens as providers grapple with rising compute costs and abuse vectors. For Western readers unfamiliar with China’s media market: the report appeared on ifeng (凤凰网), a major Chinese news portal, and reflects intense community debate rather than a legal ruling. The immediate question remains: will high‑freedom “harness” tools be folded into controlled vendor ecosystems like Anthropic’s new Cowork offering, or will open‑source alternatives evolve to reclaim that space? The answer will shape who controls AI access and cost — platforms or the developer community.
