In this chapter, we address a number of critical questions. Is there a problem with large technology firms, or platforms, purchasing nascent competitors and suppressing competition before they can mature into vibrant competitors? Further, if there is a problem, are the current antitrust laws and the enforcement of those laws sufficient to combat the problem? If not, is there a legislative solution? In addressing these questions, we offer a clear delineation and classification scheme to differentiate potential competition, nascent competitors, and killer acquisitions. Ultimately, while classification schemes are helpful, the assessment of all horizontal acquisitions, whether the rivalry is currently happening or will happen in the future, comes down to the core analytical considerations involving competitive effects, entry, and efficiencies.
