Officials of three companies that rely on these online stores, along with Alphabet's Google and Apple executives, will testify Wednesday about antitrust concerns about their app stores, which the Senate Judiciary Committee's Antitrust Committee The chiefs said on Monday.
Participating in the hearing will be Google Government Senior Director of Affairs, Wilson White, and Apple's Chief Compliance Officer, Kyle Ander, as well as Spotify's Chief Legal Officer, Horacio Gutierrez, Chief Legal Officer of the match, Jared Sine. And Kirsten Daru, Tile's General Counsel.
The list of witnesses was announced by Senator Amy Klobuchar, chairman of the Antitrust Committee, and its top Republican, Mike Lee.
Music streaming service Spotify and dating app Match have criticized the App Store of both tech giants, while Tile, whose app helps people find items, has focused on Apple.
App manufacturers have long complained that mandatory revenue sharing and strict inclusion rules in Apple's App Store for iPhone models and iPad devices and Google's Play Store for Android devices constitute anti-competitive behavior.
Four tech giants - Apple, Amazon, Facebook, and Google - have been under scrutiny for more than a year as diverse as data breaches, allegations of hate speech and suppression of conservative voices, and repressive violations.
