Censorship can take many forms, from burning books to restricting what information is available on the Internet for the citizens of an entire country. At its most basic, it's all about the control of information. Whoever owns the access to information can decide what people learn and what they do not. This can be governments, private companies, mass media - any group that in some way controls access to information. But why?
