Framing discussions around cause of death as privacy is a double standard. If you say someone died in a car crash, nobody gasps and tells you to respect the deceased's or their family's privacy. It's so extreme that is anyone even brings up privacy with regard to a death or cause of death everyone assumes they committed suicide, or did something criminal that ended in their death, or something else negative. Cause of death is posted in the newspapers and otherwise discussed in public all the time, there is no right to privacy around that piece of information.
