I agree with you completely. This will be a double edge sword. The problem I see with this a person of ethics will stay ethical. If I become a part of a group that support a code of ethics that I am to follow. What support does the Code of Ethics give me? If my employer interprets it one way and it is ok and my next manager comes back and uses the Code of Ethics set by the DBAs Code of Ethics and terminates me. What good is the Code.

If someone doesn't have this already then a code isn't going to change things.
