You have to remember, this guy's story started 10 years ago. Many schools just contract this sort of thing to a 3rd party. My school used Websense, you could easily bypass their solution by using https or simply having google translate the site from english to english. Additionally, you also assume that there is a formal IT staff. An old roommate I had used to be in charge of selecting the hardware for the computerlab in his small town school. He was a student, his school was too small to have a real IT staff.
