Yes, but that is not what the word hubris means. It means pride in the seven deadly sins sense. The pride that comes before a fall. Hubris would not mean working hard to reduce the scope for criticism. It would mean not accepting valid criticism because you think you are better than the critics.
He could have just used the word "pride" (which is far broader and has positive meanings too) instead. In some ways "ambition" might be a better fit.
