Trying to avoid antitrust suits, Google systematically told employees to destroy messages, avoid certain words and copy the lawyers as often as possible.
The encryption battles of the early 1990s focused primarily on two issues: restrictions on the export of encryption technologies and the National Security Agency’s (NSA) attempts to introduce a chipset called the Clipper chip to network technology. The first was the result of Cold War era laws designed to control the diffusion of sensitive technologies, including encryption software. This became an issue in the early 1990s when encryption software became commonplace in web browsers. In 1996, President Clinton signed an executive order that loosened restrictions after technology companies claimed that the export controls on encrypted products hurt their sales.
The National Security Agency (NSA) announced the Clipper chip in 1993. The chip was a piece of hardware designed for phones which would provide encryption on communications while also producing an encryption key and making it available to the NSA. After backlash from civil liberty groups, findings of technical vulnerabilities in the chip, and low adoption rates despite incentives, the program ended in 1996.
