On Wednesday Patently Apple posted a report titled "The U.S. House of Representatives is working to introduce Five Antitrust Bills in the next week that will Squarely affect Apple and its App Store along  with Google Play and Amazon.

This morning it's being reported that the scrutiny on big tech continues with executives from Google and Amazon head the list of witnesses for a hearing before the Senate Judiciary Committee's antitrust subcommittee next week, along with an executive from speaker maker Sonos Inc, which has been critical of the two tech giants.

Ryan McCrate, an associate general counsel, will speak for Amazon while public policy specialist Wilson White will testify for Google, said Senators Amy Klobuchar, chair of the panel, and Mike Lee, the top Republican, in a statement.

The Reuters report on Yahoo! News further adds that Sonos General Counsel Eddie Lazarus will testify at the hearing, set for Tuesday.

In congressional testimony in 2020, Sonos CEO Patrick Spence accused Google and Amazon of using their dominance of search and online retail, respectively, to subsidize the smart speaker market and, potentially, dominate the market for other smart home devices. Amazon makes Echo smart speakers and the virtual assistant Alexa while Google makes the Nest series of smart speakers.

The hearing takes place at a time of extraordinary antitrust scrutiny of the biggest U.S. technology companies including Apple. One result has been a series of investigations and several federal and state lawsuits filed against Google and Facebook.

Patently Apple also posted a report on Wednesday titled "A Preliminary EU Commission Report Claims that Digital Assistants from Apple, Amazon & Google may violate Anti-Competitive Practices."
