Re: "And now they're redefining the notion of ethics"
According to 'Fowler's', ethics is the principle, morals the practice; by which means it is concluded that ethical and moral (adjective) are much the same. Additionally that the term 'ethical' is often used because 'moral' has connotations of sexual 'misbehaviour'. Oh for the days UK public servants read and quoted these (thought-provoking, not necessarily absolutely definitive) sources.
