(Graeme Jennings/Pool via AP)WASHINGTON Congressional lawmakers finally got a chance to grill the CEOs of Big Tech over their dominance and allegations of monopolistic practices that stifle competition. While the executives faced hostile questioning and frequent interruptions from lawmakers of both parties, little seemed to land more than glancing blows. But Stephen Beck, CEO of the management consulting firm cg42, said the tech companies and their brands emerged relatively unscathed. As Democrats largely focused on market competition, several Republicans aired longstanding grievances, claiming the tech companies are censoring conservative voices and questioning their business activities in China. While forced breakups may appear unlikely, the wide scrutiny of Big Tech points toward possible new restrictions on its power.
