The match that wasn't

Currently, a suicide checkers match is being played between Europe and the US on 10 boards. You can view the games online! Suicidal Cake should have played on the 11th board against an American program, but some human players didn't want the programs participating. I can understand that people don't want to play against programs (after all, I should have played against a chess computer in a Swiss tournament in 1991, and decided to forfeit the game rather than play!), but I don't quite understand the objection against two programs playing each other. In fact, I cannot understand at all that the human experts aren't interested in seeing what the programs play!
