Google CEO Sundar Pichai is set to testify Monday in Washington, DC, where he will reportedly be questioned about encouraging his employees to keep their messages private. The company has a long-documented history of frustrating legal discovery by using private messaging tools that don’t keep logs of conversations. A lawyer for the DOJ explained in court, “So what did Google do? They destroyed documents for years because they knew their conduct violated the antitrust laws. They turned history off, Your Honor, so that they could rewrite it here in this courtroom.”
