Last week, hundreds of Google workers, outraged by the federal government’s mass deportation campaign and the killings of Keith Porter, Alex Pretti and Rene Good, went public with a call for their leadership to cut ties with ICE. The employees are also demanding that Google acknowledge the violence, hold a town hall on the topic, and enact policy to protect vulnerable members of its workforce, including contractors and cafeteria and data center workers This week, the number of supporters has passed 1,200; the full petition is at Googlers-Against-Ice.com.

As the signature count rises, employees say that Google is working to stifle speech critical of its ICE contracts: censoring posts on its companywide forum Memegen, issuing warnings to workers who post ICE-related content, and ignoring their calls to address the issue both privately and publicly.
