Many in the anti-cable camp have scientific or technical backgrounds, and they usually possess both a greater understanding and appreciation of the principles underlying the issue than most laypersons. Their training and their jobs require them to apply these or similar principles all the time, so it's something ingrained into them and part of the culture. In my own field the professional association lists this short code of ethics. Numbers three and five (and six) are most relevant to this discussion:
I'd say number seven and number ten are the most relevant, but to each their own
7. to seek, accept, and offer honest criticism of technical work, to acknowledge and correct errors, and to credit properly the contributions of others;
10. to assist colleagues and co-workers in their professional development and to support them in following this code of ethics.
