I think that the problem is that some sponsors are against computers.

I do not think that less humans will play in tournaments if they know the prizes
for humans are the same and also that everyone has to play with the computer.

Maybe there are some humans who will not play in this case but there will be
other humans that will be happy to play computers because they believe that they
can get better results against computer relative to other humans with similiar
rating and improve their chance to win prizes.
