Given that DuckDuckGo is in the business of forwarding email, they MUST use confirmed opt-in to avoid having someone mistype an email address. It’s not just the domain part that’s in consideration here, they need to ensure that typos don’t happen on the left hand side as well. I’d argue that typos on the LHS to different are a bigger problem than the occasional hit to a spamtrap as they’re forwarding PII to the address.
