There is currently a great deal of interest in online competition, particularly involving large tech firms such as Google, Apple, Facebook, Amazon, and Microsoft (a group commonly known as “GAFAM”). In this essay I examine several issues involving these firms that have often come up both in the popular press and academic discussions. The goal of this paper is to examine the facts about the alleged seven deadly sins of tech: competition, innovation, acquisitions, entry, switching costs, entry barriers, and size. I argue that when you look at the facts, it is clear that competition among tech firms is working well, and this has yielded many positive outcomes for consumers and the economy as a whole.

当前，在线竞争引起了极大的兴趣，特别是涉及大型科技公司，例如Google，Apple，Facebook，Amazon和Microsoft（通常称为“ GAFAM”的组织）。在本文中，我研究了涉及这些公司的几个问题，这些问题经常在大众媒体和学术讨论中浮出水面。本文的目的是研究有关所谓的七项致命技术犯罪的事实：竞争，创新，收购，进入，转换成本，进入壁垒和规模。我认为，当您查看事实时，很明显，科技公司之间的竞争正在顺利进行，这为消费者和整个经济带来了许多积极的成果。
