Google is accused of relying on pieces of its code within websites that use its analytics and advertising services to scrape users’ supposedly private browsing history and send copies of it to Google’s servers. Google makes it seem like private browsing mode gives users more control of their data, Amanda Bonn, a lawyer representing users, told Koh. In reality, “Google is saying there’s basically very little you can do to prevent us from collecting your data, and that’s what you should assume we’re doing,” Bonn said.

Andrew Schapiro, a lawyer for Google, argued the company’s privacy policy “expressly discloses” its practices. “The data collection at issue is disclosed,” he said.Another lawyer for Google, Stephen Broome, said website owners who contract with the company to use its analytics or other services are well aware of the data collection described in the suit.

So, Chrome specially let their tools track you adding the into secret white list, but not any competitor or site author. Typical monopoly thing.
