I think they want the free advertisement, like Apple with its “sent from iPhone” addendums. But “sent from iPhone” is sometimes useful, and significantly shorter. If they just left it at “edited with copilot” I think it would be tolerable
I don't think the issue is the sign-off so much as that an existing PR was edited. Claude Code signs off when creating PRs and nobody seems bothered. But it won't edit an existing PR, and it won't sign off if I simply ask it not too (which I've automated). Editing any PR it touches - including one authored by someone else - is downright rude.
That's exactly where my mind went. It's zero percent more insulting to me than 'sent from my iPhone.'
If you don't want copilot garbage in your PRs, maybe don't use copilot to create or edit them?
"Sent from iPhone" doesn't contain a call to action, and doesn't exalt the features of the product.

No, it is still an advert, and not useful in the least.
