Why did the judge comment that Google's data collection was 'confused'?

Web browsers such as Google Chrome have a secret mode (privacy mode) function that allows you to browse without recording your browsing history. At a hearing on Google's 'data collection issues for users using privacy modes,' a judge reportedly commented that he was 'confused' about data collection in privacy modes, raising doubts about Google's attitude. ..

Privacy mode is a function that allows you to browse websites without saving data such as caches of website images and texts and cookies, unlike normal browsing. Therefore, when you end the session, the history and cache will be deleted from the browser, and you will not be able to check the browsing history later.

On the other hand, privacy mode is just a browsing mode that does not leave history in the browser, and does not provide users with complete anonymity. As with normal browsing, the user's IP address will be notified to the website, and the activity may be known to the Internet service provider you use.

A hearing related to the proceedings was held on February 25, 2021 in the Federal District Court in San Jose, California. During the hearing, Judge Lucy Koh reportedly cast doubt on Google's stance, commenting that it was 'confused' about Google's data collection practices as described above.

Meanwhile, Google's lawyer Andrew Shapiro claims that Google's privacy policy explicitly discloses data collection in privacy modes. Opening the incognito mode tab in Chrome states that activity may be known to 'visited websites', 'employers or schools (holding your device)', and 'your internet service provider'. It has been.

'The owners of websites that use Google's services are also aware of the data collection in question in the proceedings,' said Steve Blum, a lawyer at Google. The federal court's website also uses Google's services, so the court argued that it should be aware of Google's data collection practices.

In response, Judge Kor expressed concern about the possibility that the court's website unknowingly disclosed visitor data to Google. We asked you to explain 'the user information that Google collects from the court website and what it is used for.'
