The chief executives of four US technology giants endured withering, rapid-fire questioning for more than five hours from lawmakers who accused their companies of using their power to crush rivals and squash competition.
Alphabet Inc’s Google, Facebook Inc, Apple Inc and Amazon.com Inc were criticised for the power they wield over digital markets: Google’s control over Internet search and online advertising; Apple’s tight grip over apps; Facebook’s acquisition of rivals; and Amazon’s leverage over third-party sellers.
