Anthropic thinks they're Apple. They're actually hypocrites.

Summary based on the YouTube transcript and episode description.

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.
