A list that names seven employees who say they quit their jobs at Google over a lack of corporate transparency is circulating within the company’s ranks. The departures follow the controversial revelation of Google’s work on Project Dragonfly, a censored search app for the China market. Employees shared the list of names on an email list dedicated to discussions of ethics and transparency issues at Google.

While current employees declined to provide the list itself or to specify most of the names on it, three sources familiar with the matter confirmed the existence of the list, which is made up largely of software engineers whose experience at Google ranges between one and 11 years. Google declined to comment on the list.

One of the names on the list is that of former Google senior scientist Jack Poulson, who worked for the company in Toronto before resigning over Dragonfly last month. Like the majority of Google employees, Poulson first learned about Dragonfly from the Intercept’s story about the project, which said Google had already demonstrated Dragonfly for the Chinese government and that it could launch within six to nine months. Poulson said he was “shocked” by the news.

“If it was true, I was pretty sure immediately I couldn’t continue working there,” he told BuzzFeed News.

When Poulson resigned in August, he said he only planned to share his concerns about Dragonfly with those inside Google. But when Google didn’t respond to a group of human rights organizations that presented it with a letter arguing that Dragonfly is unethical and asking the company to kill the project, Poulson felt compelled to share his opinion with the public.

“I’m offended that no weight has been given to the human rights community having a consensus,” he said. “If you have coalition letter from 14 human rights organizations, and that can’t even make it into the discussions on the ethics behind a decision, I’d rather stand with the human rights organizations in this dispute.”

Regarding Poulson’s departure, a spokesperson for Google said, “It is our policy to not comment on individual employees."

The revelation of Dragonfly provoked an immediate backlash within the company’s rank and file, who have high expectations for transparency from executives because of Google’s stated corporate values. One employee who’d been asked to work on the project decided to quit, another transferred teams, and internal forums were flooded with thousands of posts, comments, and emails debating the ethics of the project.

In the days that followed, over 1,000 employees signed a list of demands, called a “Code Yellow on Ethics,” that included calls for increased employee oversight and third-party ethical reviews of certain projects. In his resignation letter, Poulson said he called for Google executives to address the Code Yellow demands. To date, that letter has over 1,700 signatures, and those interested in discussing issues of ethics and transparency have been planning to meet in person, sources said.
