He has made important contributions, and at one point could have been considered so, but what has he created lately that is worthy of the title? Some titles like "doctor" are really indicative of the education, not of being a current practitioner, but "hacker" is not one of those titles.
Maybe someone should create an official overseeing body of hackers like "The U.S. Board of Hackers" and a social organization called "The Hacking Society" to go with it, and I could go to school and come out and in front of my name on all formal letters would thereafter be "Hacker". But, until then, I think he was but isn't.
