Steve Lohr in his article “Data Could Be the Next Tech Hot Button for Regulators” quotes Maurice Stucke:
“Maurice Stucke, a former Justice Department antitrust official and a professor at the University of Tennessee College of Law, who also spoke at the gathering, said one danger was that consumers might be afforded less privacy than they would choose in a more competitive market.
The competition concerns echo those that gradually emerged in the 1990s about software and Microsoft. The worry is that as the big internet companies attract more users and advertisers, and gather more data, a powerful ‘network effect’ effectively prevents users and advertisers from moving away from a dominant digital platform, like Google in search or Facebook in consumer social networks.”
