Anthropic provides subsidized access to Claude models through Claude Code. It is well understood to be 'a loss leader' so that they can incentivize people to use Claude Code.
OpenCode lets people take the Claude-Code-only-API-Key, and lets them use it in a different harness. Anthropic's preferred way for such interaction is getting a different, Claude API key (and not Claude Code SDK API key).

A rough analogy might be something like getting subsidized drinks from a cafe, provided you sit there a eat food. What if someone says, go to the cafe and get free drink and come sit over at our cafe and order food. It is a loose analogy, but you get the idea.
Thank you, I understand all of this. My question was about the reference to "petty and bitter."

You have zero proof for this claim. It's like people read somewhere that stuff and keep spitting it out again and again without understanding..
