In the wake of Big Tech’s growing power, much attention has been directed to the Federal Trade Commission as the regulatory force for monitoring the technology industry. But scholars are largely divided on the issue of whether privacy exists within the scope of antitrust law. Using the 2008 acquisition of DoubleClick by Google as a case study, this article argues that privacy is an antitrust issue and should have been considered in the FTC’s merger review process for the ways it affected both competition and consumer welfare. The article examines the role of consumer data in fortifying Google’s barriers to entry, squashing innovation, and reducing choice in the marketplace, and considers the invasion of data privacy as an issue of consumer protection. The article argues that the foundation for evaluating privacy within the merger review already exists, as Section 5 of the FTC Act gives the Commission special responsibility to uphold these values and interpret its review process in order to keep up with a changing market structure. More than a decade later, these lessons remain relevant, as antitrust law experiences a resurgence in the United States.

Google-DoubleClick合并：联邦贸易委员会关于保护隐私的局限性的教训

随着大技术力量的不断增强，联邦贸易委员会已成为关注技术行业的监管力量，引起了很多关注。但是，在反托拉斯法范围内是否存在隐私问题上，学者们意见分歧。本文以2008年Google对DoubleClick的收购为案例研究，认为隐私是一个反托拉斯问题，在FTC的合并审查过程中应考虑到隐私对竞争和消费者福利的影响。本文探讨了消费者数据在强化Google的进入壁垒，挤压创新和减少市场选择方面的作用，并将数据隐私的入侵视为消费者保护的问题。该文章认为，合并审查中评估隐私的基础已经存在，因为《联邦贸易委员会法》第5条赋予委员会特别责任，以维护这些价值并解释其审查过程，以适应不断变化的市场结构。十多年来，随着反托拉斯法在美国复苏，这些教训仍然具有现实意义。
