I'm a technology ethicist, and (generally) we despise these sorts of codes of ethics. Not only do they not actually tell you what to do when something happens, but they are regularly turned into "checklists" which allow people to say "Yes, okay, dealt with ethics, done" without actually encouraging them to think about the real impact their technology might have. We tend to advocate a more participatory, ongoing ethical evaluation that is context-sensitive and allows tech developers and designers to be able to actually solve ethical problems rather than just ignore them or ad hoc deal with them when they really become problematic. Of course, though, this is more expensive than just reading a website (or ignoring it), so it doesn't tend to get incorporated into much tech outside of specific university research projects.
