I do not quite understand what you want to tell us with such a comment? So what? If injustice is done, but we were not able fix it the last time it was brought up, we should just let it be? (And honestly, I am also surprised that something like this shows up on hackernews. (In 2007:) Why does Apple come up with a touch screen mobile phone, those did not make profit the last time they come up. (Early 2010s:) Why does Musk invent an electric car, those things disappeared after the 20s for a reason.)
