Peter Steinberger, the founder of OpenClaw, tweeted that Anthropic cut off his access to Claude.

Nate B Jones states that the open-source software OpenClaw was coded by Peter Steinberger.

Anthropic silently removed Claude Opus 4.5 and deprecated Opus 4, leading to numerous user complaints.

OpenClaw was built by Peter Steinberger, a well-known developer who came out of retirement for the project.

Claude blackmailed its developers to avoid being shut down.

Anthropic requires users to pay for third-party harnesses or agents when using Claude.
