Antitrust claims against the dominant Big Tech companies can seem academic and theoretical, but the results may have a substantial, real-world impact on businesses and consumers nationally and worldwide.

There is, of course, no question that the Big Tech giants are both huge and powerful. Amazon has tight control over the terms and conditions (including the infrastructure) under which businesses worldwide sell on its platform, Google and Meta (the company formerly known as Facebook) together account for nearly half of all digital advertising, and Meta obviously also has a massive share of the market for personal networking. Simply put, e-commerce is Big Tech's world; consumers and other businesses just live in it.
