Exactly. While the majority of human social games are nonzero sum, playing against the oil industry is zero sum. In order for human life to continue to exist, the oil industry must not exist. This is an extermination game.

Within a zero sum game, there's no room to deal or ask for concessions because the survival of each side depends on winning. Corporations focus on immediate profits, so they don't account for the long term. It's useless to think about them as rational actors, because they are not. They have one objective and they are not capable of accounting for the long term effects of that because if they did, they couldn't exist anyway. If the political system is poisoned by the oil industry, then protests can't really work. This game is the same game as nuclear war, after the war has started. Asking to stop the war at that point wouldn't make any sense. The only way to survive is to destroy the enemy, as fast as possible, by any means necessary. To not do everything possible to end petroleum is to accept death.
