Amazon, Facebook, Apple, and Google CEOs were testifying for more than five hours at a hearing of the US House Congressional Judiciary Committee, NV reported.
Mark Zuckerberg (Facebook), Tim Cook (Apple), Sundar Pichai (Google), and Jeff Bezos (Amazon) participated in the hearing via video link.
The heads of tech giants answered questions over the investigation into their use of non-competitive practices. The committee's investigation revealed that these companies were abusing their power.
According to the Wall Street Journal, the CEOs have been grilled during the hearing.
It noted that these companies collect data about competitors to protect their position, suppress competition by buying up other players, and copying their products.
The questions covered many issues, from the moderation of posts on social media to how companies have conquered large market shares. Tim Cook was more fortunate than the rest - he was asked fewer questions.
Zuckerberg was criticized for the fact that the company is buying up competitors (in particular Instagram), allowed Russia to interfere in the 2016 presidential elections, and does not change the moderation rules. The main complaint against Bezos, who attended the Congressional hearing for the first time, was that he gets data on successful companies and products and copies them to create her own. Pichai has been accused of using data to suppress competition, cash in on ads, and manually edit searches.
Apple has been criticized for abusing the App Store.
Technology CEOs responded by saying they are keen to remain politically neutral and focus on serving consumers rather than fighting competitors.
