“Most people who use the Internet seem take its nature and characteristics for granted, like we take air and water for granted. Your relationship with air and water — what you can do with it or within it — is for all practical purposes an unchanging fact of nature. What you can or cannot do with or on the Internet, however, is the result of specific decisions and actions by individual human beings who hold different motivations — be they political, cultural, social, academic, economic, or business motives. The actions themselves take different forms: programming, engineering, design, business, or legislative. These decisions and actions determine things like how much privacy you have, how easily your digital activities can be tracked and by whom, how your online identity relates to your offline identity, and to what extent you can have more than one online persona.”
