Good Question! Only the DH Abuse Team could tell you for sure how they would view it. This is a “customer-to-customer” forum and, while DH staffers do occasionally pop in, they rarely post - most of the participants here are customers just like you and I.
That said, I feel safe in saying they would respond to a DMCA take-down notice - other than that I could only guess. There is a “new” resource that answers many question about how DH views and handles abuse issues at Abuse.dreamhost.com; you might find that information interesting or helpful.
That code has clearly “escaped into the wild”, and will never be “recaptured” - you can’t “unfire” a gun.
