i do not understand what do you mean.
what is unfair?
in every tournament you can see that the competitors are playing against
different opponents. that´s the soul of swiss-tournaments.

anyway: if you want to see a disadvantage than those who have more than one
program, have the disadvantage.

suppose that the person with two programs is high ranked with both programs. so
he cannot play against himself, he has to play against lower rated opponents
with both programs, which will have a bad effect to his bucholz. so he has to
get a half point more than the others if he wants to win. a clearly
disadvantage, because also the low ranked programs are nearly equal strong as
the high ranked ones. there is not a single program that is remarkable weaker.

anyway, we shouldn´t build all constructions possible. it´s only a theoretical
discussion.
