Yet, somehow, the data collectors can manage to record individuals’ purchase histories, their airline seat preferences, and so on. There is no reason why they could not also record how and by whom each piece of such information can be used.
但不知何故数据采集者却可以保存个人购买历史，他们的飞机座位偏好等等诸如此类的记录。因此无法保存信息的使用者及使用方式根本不是理由。
