Google under fire for installing a Chrome extension surreptitiously and listening to conversations of Chromium users without consent. Google removed the extension from Chromium, the open-source version of the Chrome browser. The extension in question is “Chrome Hotword,” which was responsible for offering the browser’s famous “OK, Google” functionality. Google defended itself, arguing the ability to use “Ok Google” commands and enable the extension is an opt-in feature. Google doesn’t deny installing the black box code into Chromium browser, but the company doesn’t consider itself responsible for other web browsers that include the code.
