Google has been vague about Project Dragonfly ever since it first came to light. Leaked documents indicated that the China-centric search app would automatically identify websites blocked by the country's so-called Great Firewall, and simply remove them from search results. This would include information on free speech and political opposition, as well as any negative references to authoritarian governments.

While Google did confirm that it was working on a project codenamed Dragonfly, it wouldn't give any further details on it, other than to say its development was going well. However, Dragonfly faced global backlash once more details about it emerged, with Amnesty International organizing a protest against the project and Congress hauling Google boss Sundar Pichai out for questioning.

While the episode shines a light on Google's enormous capabilities for ethically-dubious activities, it does again demonstrate that the company is willing to respond to feedback. Last year, after the tech giant picked up a massive -- and controversial -- contract with the Pentagon, more than 4,000 employees signed a petition against the deal and a dozen engineers left the company. As a result, Google pledged not to renew the contract. However, whether Dragonfly was dropped because of employee rumblings, or because of other unspecified project developments, is unclear.
