Great, here’s how to remove it from your commits:

Run git commit --amend

Your text editor will open. Delete the line: Co-authored-by: Github Copilot <noreply@github.com>

Save and exit

Force push the change: git push --force-with-lease

Or people could instead not use Microslop software, easy fix for the AI bullshit. But yeah of course you're technically right.
