I just skimmed it, personally I'm not convinced by what I saw: the premise that professional ethics is not personal ethics, while true, is not really meaningful to technical disciplines. In my engineering ethics and professional practice courses I never saw anything "nontechnical" in our ethics, most of it was don't do stuff you're not qualified for and awareness of applicable law. The problem with ethics is that there is a vocal group that wants to turn their personal ethics into our professional ethics and impose on software a bunch of judgements that are super subjective (and thus outside the profession). While I wouldn't be surprised to find professional conduct in other engineering disciples to be getting similarly hijacked these days, I think the only sensible way to professionalize software would be voluntary and technically grounded, not dealing with what you'd put in the realm of personal ethics at all.
