Few companies have more riding on proposed privacy legislation than Alphabet’s Google and Facebook. To try to steer the bill their way, the giant advertising technology companies spend millions of dollars to lobby each year, a fact confirmed by government filings. Not so well-documented is spending to support highly influential think tanks and public interest groups that are helping shape the privacy debate, ostensibly as independent observers. Bloomberg Law examined seven prominent nonprofit think tanks that work on privacy issues that received a total of $1.5 million over a 18-month period ending Dec. 31, 2018. The groups included such organizations as the Center for Democracy and Technology, the Future of Privacy Forum and the Brookings Institution. The actual total is undoubtedly much higher — exact totals for contributions were difficult to pin down. The tech giants have “funded scores of nonprofits, including consumer and privacy groups, and academics,” said Jeffrey Chester, executive director at the Center for Digital Democracy, a public interest group that does not accept donations from Google or Facebook. Further, he says, their influence is strong. The companies have “opposed federal privacy laws and worked to weaken existing safeguards,” Chester said. Accepting donations from these “privacy-killing companies enable them to influence decisions by nonprofits, even subtly,” he said.
