YouTube has removed thousands of propaganda videos from late al-Qaeda-linked cleric Anwar al-Awlaki amid mounting pressure from governments and counterterrorism advocates. "It's a watershed moment on the question of whether we're going to allow the unchecked proliferation of cyberjihad," Mark D. Wallace, former diplomat and current CEO of the Counter Extremism Project - a research organization that long called for Awlaki's videos to be taken down online. "You just don't want to make it easy for people to listen to a guy who wants to harm us."
