Anthropic thinks they're Apple. They're actually hypocrites.
Theo (t3.gg) argues Anthropic violated Apple’s iMessage TOS while simultaneously sending legal threats to open-source devs for doing the same thing with Claude’s subscription endpoint.
- Anthropic employee publicly promoted an iMessage plugin for Claude Code that violates multiple Apple TOS clauses, including reverse-engineering and automated server access.
- The same week, Anthropic sent legal demands forcing Open Code to remove a plugin that let users route their Claude Code subscription through a third-party UI.
- Anthropic’s Claude Code subscription uses a separate OAuth endpoint distinct from the pay-per-use API; Anthropic explicitly forbids using that OAuth token outside Claude Code or Claude.ai.
- Developer Matt PCO spent nearly a month trying to get a straight policy answer from Anthropic about building an open-source Claude Code wrapper and received only non-committal apologies.
- OpenAI, GitHub Copilot, Kilo, and Open Code all allow subscription inference to be used across third-party harnesses; Anthropic is the sole major holdout.
- Anthropic’s Claude Code TypeScript SDK is closed-source despite the Python SDK being open-source, which Theo frames as deliberate lock-in.
- Epic Games did less than what Anthropic’s iMessage plugin does and had all Mac developer machines locked by Apple; Theo expects similar consequences for Anthropic.
