Google made a new push for more defense work this week, with an approach to cloud computing it thinks should appeal to government customers. Until now, Google has mostly sat those lucrative contracts out, in part because it’s faced pushback from some employees. Other tech companies have, too. But new reporting shows Big Tech is doing a lot more defense and law enforcement work than perhaps was realized. I spoke with Jack Poulson, a former senior research scientist at Google. He now runs the nonprofit Tech Inquiry and has reported on the thousands of subcontracts tech companies have with defense contractors.
