Do you want the long version or the short one? Since the other questions are
discussed elsewhere I give you the short answer.

1. Simply because we have too much contradictions.

2. Simply because it was not just a sport event.

3. Simply because the IBM and DB side had called the event 'science'. Which is
totally normal since the machine was a scientific project over all the years.

4. Simply because we have Garry Kasparov and the game scores. I would doubt with
all respect that Ken Thompson is equal to Kasparov when it comes to a game of
chess. Also, in the question of the psycho war, Ken Thompson was not on the side
of the DB team. He criticised the way they treated Kasparov. So he might have
understood the terrible situation Kasparov was in. As a scientist he knew what
that meant for the interpretation of the results. All IMO of course.
