The Internet and Leaderless Terrorism

The Internet and social media play a significant role in recruiting and radicalizing lone-wolf and leaderless terrorists. The emergence of evolving technology, such as the Internet offers like-minded persons the ability to operate within virtual communities without direction from any formal organization. This sort of activity has given life to the creation of leaderless terrorism, also known as leaderless resistance. The Internet provides all of the tools, motivation, and a new operational strategy, requiring no command or control from any group or organizational 'leader."
Arresting and prosecuting these sorts of activities under the guise of "terrorism" affords the government many investigative and prosecutorial advantages, while it also stifles political dissent to protect private economic gain at the expense of the environment.
How has the Internet changed the time-tested traditional hierarchy of terrorist organizations to the new leaderless terrorism model? Be sure to include relevant examples to support your position.
