Credit: WikiMedia Commons The Senate Judiciary Subcommittee on Competition Policy, Antitrust, and Consumer, which is headed up by Sen. Amy Klobuchar, held a hearing on "Protecting Competition and Innovation in Home Technologies." Sonos legal chief Eddie Lazarus was one of the key witnesses in Tuesday's hearing. Most of the commentary during the hearing focused on dominant market giants Amazon and Google, with representatives for those companies also testifying on Tuesday. However, Lazarus also criticized some of Apple's walled-garden HomeKit policies. For example, although Apple is bringing Siri to third-party manufacturers, Lazarus took issue with the way Apple is rolling out support.
