The unmodified tit for tat strategy has a weakness, every tit for tat interaction requires a certain amount of resources and human time, and if two agents that judge each others actions as uncooperative follow that strategy they will both get into a retaliation chain where the one with the most resources wins. In the early stages communes are likely to be in a situation of having limited resources and can't use that strategy.
