Annoying for sure, but one benefit of this approach is due to forwarding. For the moment, let's assume you have a newsletter you enjoy. If you forward an instance of that newsletter to your friend, and they aren't expecting it, they might hit unsubscribe. With one click, they'll prevent you from receiving future newsletters.
I think the better approach is simply showing the "Intended for [email protected]" next to Unsubscribe, but I could see why they ask for your email.
