Thing is, unsubscribe links are often an "inform spammers that this mail address is in use" link. Even the ones Gmail offers up.
If I didn't click their button to subscribe, I'm not clicking their button to unsubscribe. Who's to say they won't just "sign me up" again after a while? In fact I know several large US corporations which routinely sign you up for notifications again after a few months.
If you didn't click the button, then of course, you don't send the unsubscribe message.
If you did subscribe to a newsletter and no longer want to receive it (which is the majority of these cases), then the unsubscribe action is the logical thing to do.
