Sundar Pichai Joins Other Big Tech CEOs at Key US Antitrust Hearing

Pandemic Strength

David Cicilline said the coronavirus outbreak has strengthened the clout of the four, saying: "They are likely to emerge (from the pandemic) stronger and more powerful than ever before."

Some lawmakers sought to play down the competitive danger of the companies, which have won praise for innovating and introducing new technologies and offering lifelines during virus lockdowns.

"Being big is not inherently bad," said Jim Sensenbrenner, a Republican from Wisconsin. "Quite the opposite, in America you should be rewarded for success."

Abusing Platforms?

Lawmakers also put spotlights on problems with tech companies operating platforms relied upon by rivals.

Sundar Pichai was pressed regarding whether Google's ad platform tactics hurt other internet players such as news outlets.

Apple's Cook faced tough questioning over the market power of the company's App Store and its treatment of developers.

"We treat all app developers the same," Tim Cook said. "We do not retaliate or bully people."

Jeff Bezos, in his first appearance before a congressional committee, defended Amazon's dealings with third-party sellers after a blistering attack from Cicilline.
