You're conflating two different things. When an LLM writes a commit, it should take credit. I see nothing wrong with it adding:
> Co-Authored-By: Claude Opus 4.6 [email protected]
Compare that to the message the article is talking about:
> Quickly spin up Copilot coding agent tasks from anywhere on your macOS or Windows machine with Raycast (https://gh.io/cca-raycast-docs).
It's not just mentioning it was written via Copilot, it's explicitly advertising for another product.
I understand what it's doing. I'm just saying that I'll take any signals I can get that someone is lazily submitted LLM-generated work without edit or review.
If you saw this line in a commit, you'd know exactly where it came from.
