[Commentary] What more can be said about the Internet's role in the popular uprising that has shaken the Iranian regime since its widely contested election? The power of open social networks is undisputed. The Internet's three favorite offspring -- Twitter, Facebook and YouTube -- have been heralded by mainstream media as flag-bearers for a new era of citizen journalism and activism. But the open Internet's power cuts both ways: The tools that connect, organize and empower people can also be used to hunt them down. The companies that profit from sales of this technology need to be held to a higher standard. Of particular concern is the use -- and easy abuse -- of Deep Packet Inspection. DPI is a content-filtering technology that allows network managers to inspect, track and target content from users of the Internet and mobile phones, as it passes through routers on the information superhighway.
