Suicide is something that happens due to a cause, generally mental health issues or extreme physical pain. “died by suicide” removes culpability from the person who has lost their life and allows a discussion about the disease or disorder from which they were suffering. Consider a case where someone got shot. Should the headline read, "died by stepping front of a gun" or "shot dead by a gun"?
