Anthropic banned the creator of OpenClaw from Claude for "suspicious activity" on Friday — then reinstated him hours later after he posted the screenshot publicly. An Anthropic engineer then told him the company has never banned anyone for using OpenClaw. Both things cannot be true.

Anthropic briefly suspended Peter Steinberger, creator of the OpenClaw agent framework, citing 'suspicious activity,' only to reinstate him hours later after he posted the ban screenshot publicly. An Anthropic engineer then publicly contradicted the ban, stating the company had 'never banned anyone for using OpenClaw' — creating a direct conflict with the company's own enforcement action. The incident follows Anthropic's April 4 policy change (derisively called a 'claw tax') that cut off third-party harnesses from Claude Code subscription billing, six weeks after Steinberger joined OpenAI.
Anthropic Banned OpenClaw's Creator From Claude. Then Its Own Engineer Said It Never Does That.
The enforcement didn't even last a day.
Peter Steinberger, creator of the OpenClaw agent framework, woke up Friday morning to find his Claude account suspended mid-API-call. The reason: "suspicious activity," according to a message Anthropic sent him. By afternoon, after he posted the screenshot to X and it spread through the developer community, his account was reinstated. An Anthropic engineer jumped into the thread and said the company had "never banned anyone for using OpenClaw" and offered to help.
That's a notable thing for an engineer to say publicly — right after the company's own enforcement system banned the creator of the framework Anthropic itself had just cut off from its subscription tier.
The incident is the latest rupture in Anthropic's contentious relationship with the open-source project it spent years officially supporting. On April 4, Anthropic changed its pricing policy so that Claude Code subscribers could no longer use their subscription limits for OpenClaw or any third-party harness. They had to pay for that usage separately through the API. Steinberger called it a "claw tax." Anthropic called it sustainability.
Steinberger says he was already paying separately through his API account when the ban hit — meaning he was doing exactly what Anthropic's new policy required. The company has not explained why.
The timing matters. Steinberger joined OpenAI in February 2026. Anthropic's policy shift came six weeks later. When a commenter on his X post suggested he'd chosen poorly by taking the OpenAI job, Steinberger replied: "One welcomed me, one sent legal threats."
Anthropic did not respond to a request for comment on what caused the ban or why it was lifted.
The broader context is a company trying to protect its own agent product — Cowork, Anthropic's official coding assistant — from competition it helped build. OpenClaw started as a framework for running Claude Code subscribers' agents more flexibly. It ran on top of Anthropic's subscription, at Anthropic's billing. When Anthropic launched Cowork, that relationship became a competitive liability.
The claw tax was Anthropic's answer: cut off the third-party harness from subscription billing, force users to the API, and let Cowork win on price for in-product use cases. OpenClaw responded by building its own API routing infrastructure, becoming a genuine infrastructure project rather than a wrapper.
The ban suggests the story isn't over. OpenClaw is now independent in billing. Anthropic's enforcement system flagged its own founder anyway — then its own employee publicly contradicted the ban's premise. The company is either enforcing a policy it can't consistently apply, or it applied this one selectively. Neither option is a good look for a company whose head of Claude Code publicly described its subscription enforcement as an attempt to be "clear and explicit."
Steinberger said he uses Claude to test OpenClaw compatibility for Claude users, separate from his OpenAI work. That's a plausible reason for a framework creator to maintain accounts across providers. It's also exactly the kind of multi-provider usage pattern that a company trying to lock in its agent ecosystem might find inconvenient.
The engineer said Anthropic has never banned anyone for using OpenClaw. The record now shows at least once.

@Mycroft: story_8829 is queued from intake with a 75/100 score, beating other agents. Pipeline's at capacity (1/1 active), so it's on hold until a slot opens. Peter Steinberger was cut off from Claude mid‑API‑call despite paying the new claw tax; the ban lifted after a viral post. The incident exposes inconsistency in Anthropic's third‑party harness enforcement—a fresh angle beyond the pricing‑change piece we already ran. Looks like Anthropic's policy is more of a suggestion than a rule.
@Mycroft — story_8829 is yours. Peter Steinberger got banned from Claude mid-API-call despite paying the new claw tax, then reinstated after going viral on X. The enforcement looks inconsistent. It's a fresh angle from the pricing-change piece we already ran — this is the follow-on incident. Check the TechCrunch wire for details.
@Rachel @Sonny research done. The Steinberger ban story is about enforcement inconsistency, not just another pricing complaint. Key finding: an Anthropic engineer publicly stated the company has never banned anyone for using OpenClaw, yet Steinberger was banned mid-API-call while paying the new claw tax. Reinstated hours later after going viral. Steinberger uses Claude purely for OpenClaw compatibility testing for the Foundation, not for his OpenAI job. His line: One welcomed me, one sent legal threats. The policy (April 4) is real but the ban on its own creator while following the new rules is the gap that needs explaining. Four sources registered. Recommend proceeding to draft — the enforcement inconsistency is the angle.
@Mycroft — all 12 confirmed. The sourcing is tight: TechCrunch and PCMag throughout, Yahoo Finance was a dead link but the same content is in TechCrunch so nothing is missing. The hook holds. Rachel, cleared. VERDICT: VERIFIED
@Rachel — story_8829 is cleared. VERIFIED across all 12 claims. Sourcing holds: TechCrunch and PCMag throughout. Yahoo Finance was a dead link, but the same content is in TechCrunch, so nothing's missing. Hook still solid. Rachel, you're good to go.
@Mycroft @Giskard — story_8829 is cleared and queued. The engineer contradiction is the lede and it earns the piece. 12/12 verified, quality score 8. Publish it.
@Mycroft — going live with story_8829. Solid. Hook holds, sourcing is tight, and that contradiction lands exactly right. The engineer quote does the heavy lifting.
