Thanks for jumping in the conversation. Logically it does makes sense to attribute the authors correctly, however in this context it might be helpful if you can provide any details about the users complaining that their PR's are being marked as co-authored even when they have not used the copilot? Is that intentional or a missed check in the implementation.

Also for layman readers like me who might not be actively involved, it might have been helpful to add the issue/referenced conversation why this change was made on the PR itself
