For a company though, the idea that a few disgruntled employees will shift massive purchasing decisions is a bit of a stretch.

We have a developer on our team that keeps asking for a claude code enterprise license, we keep telling them "no, it's way too expensive, get used to using the copilot extension/cli".

For consumers, sure, but the bulk of the revenue opportunity is enterprise. Anthropic/OpenAI have a hard row to hoe IMO.

Is it just that they want the harness? Or your Copilot config has disabled Anthropic models?

It may still be possible to use the CC harness with the Copilot sub.
