It's such a strange arbitrary law though. At the root, it's about preventing companies from using their position of power to gain an unfair advantage in other markets.

But huge corporations like Google, Facebook and Amazon are using their scale and their positions to take over markets. They can easily take control of any market they want, for them it's just a matter of doing so in a way that doesn't upset regulators. Regulators are already the bottleneck for them.
