technically the modern moog model d's are clones of the original moogs too so equally unethical.

EDIT: "After the sale of Moog Music, production of the Minimoog stopped in the early 1980s. In 2002, after founder Robert Moog regained the rights to the Moog brand and bought the company, the Minimoog Voyager, an updated version, was released. In 2016, the company released a new version of the original Minimoog."
