I found that amusing while writing it too :P but the comment I replied to brought up vegetarianism and seemed to be making a general point about ethics vs. convenience.
I think it illustrates that people can disagree with what constitutes unethical actions - the higher the requirement that everybody agree on what is unethical, the more heinous the crime has to be. So most of us will agree on the items in your list, but eating meat or using Chrome will be harder to get consensus on.
