4 Big Tech CEOs getting heat from US Congress on competition

Four Big Tech CEOs — Facebook’s Mark Zuckerberg, Amazon’s Jeff Bezos, Sundar Pichai of Google and Tim Cook of Apple — are set to answer for their companies’ practices before Congress as a House panel caps its yearlong investigation of market dominance in the industry.

The four command corporations with gold-plated brands, millions or even billions of customers, and a combined value greater than the entire German economy. One of them is the world’s richest individual (Bezos); another is the fourth-ranked billionaire (Zuckerberg). Their industry has transformed society, linked people around the globe, mined and commercialized users’ personal data, and infuriated critics on both the left and right over speech.
