Disqualification occurs typically because you breach certain rules or guidelines regarding fair play, in which case the spot you have arrived at may not have been attainable without such advantage(s), and perhaps another player/team might have been there instead. Thus, decision is sometimes made to replace those DQ teams with others that are more deserving.
A forfeit is strictly on the player/team. They have done nothing wrong to reach the point where they are in the tournament and are there by the merits of competition and fair play. In such a case, if they choose to forfeit, there is no reasoning behind another team taking their place because each player/team has already reached where they should have.
I hope that makes sense because it quite a huge difference... and you are not just trolling me with that question. :embarrassed2:
Thank you for that clarification, I don't think it's without merit. However, I'll suggest that your definition of "forfeit" is not universal.
