> Google has written publicly about how this system works
If this is news to Hackers News, there is no way that regular Chrome users are aware of it. Saying something in a privacy policy or on a developer website just can't be enough for analyzing a person's URL data.
> This includes only listing publicly discoverable pages, only including data from users who have turned on "Make searches and browsing better (Sends URLs of pages you visit to Google)", and only including pages that are visited by a minimum number of users.
Since when does aggregating this type of data make it fair game? This is analyzing a person's URL data from their own devices. There has always been a big bright red line for browsers touching a user's browsing history. Google crossed that line.
Also, I just checked on a fresh Chrome install. The "Make searches and browsing better" option is enabled by default and buried in Chrome settings. How is that acceptable consent for analyzing a person's URL data?
