Why does the CACM article suggest that governments might use blocking technology?
Some people(see The Net Labeling Delusion) have criticized the following paragraph from the CACM article on PICS: Not everyone needs to block reception of the same materials. Parents may not wish to expose their children to sexual or violentimages. Businesses may want to prevent their employees from visiting recreational sites during hours of peak network usage. Governments may want to restrict reception of materials that are legal in other countries but not in their own. The off button (or disconnecting from the entire Net) is too crude: there should be some way to block only the inappropriate material. Appropriateness, however, is neither an objective nor a universal measure. It depends on at least three factors: 1. The supervisor: parenting styles differ, as do philosophies of management and government. 2. The recipient: what s appropriate for one fifteen year old may not be for an eight-year-old, or even all fifteen-year-olds. 3. The context: a game or chat room that is appropriate
