I had not thought about it this way before, but the penalties and scoring rules make the "one team gets 0, the other scores all the points" a less attractive strategy for the team scoring all the points and more for the zero points team. Because the best the winning team can do in that case is equal the losing team's seeding points. If Red scores 10 points and B gets zero, then they both get 10 points if Red had no penalties, and Red ends up with fewer points if they had penalties. This means that it is probably not in an alliance's best interest to cooperate in a "one alliance scores all the points, the other goes for zero" strategy if they are going to be the alliance that scores.
