That would be able to happen, but also not be able too. Many of the big tech companies are American (Asus, Apple, Alphabet, IBM, Dell, Intel, Nvidia, Microsoft, HP, Comcast, and more) and as long as the U.S. Federal Government has regulation power (basically as long as Liberals and Democrats have a say), the FCC would block a merger or buyout because it would fuck the American people and most of the world.
