NOTE: I quoted a report from an executive of DuckDuckGo attending the antitrust lawsuit against Google. This article has now been retracted from Wired:

"After careful review of the op-ed, "How Google Alters Search Queries to Get at Your Wallet," and relevant material provided to us following its publication, WIRED editorial leadership has determined that the story does not meet our editorial standards. It has been removed."

I hope we'll learn more about what Google actually does, since September 28, the court established a process allowing the Justice Department to publish more information about this case.

A Note From WIRED Leadership

@johncarlosbaez What Google actually does ... Here is an overview regarding ad markets.
It doesn’t require botching search queries.

@johncarlosbaez The antitrust perspective is that there shouldn’t be a monopoly in this space. My opinion is that individual surveillance to generate detailed personal profiles as a basis to influence behaviour is a terrible idea in principle - detrimental to security and democracy.
