Approaches to privacy can, broadly, be divided into two categories: free market, and consumer protection. In a free market approach, commercial entities are largely allowed to do what they wish, with the expectation that consumers will choose to do business with corporations that respect their privacy to a desired degree. If some companies are not sufficiently respectful of privacy, they will lose market share. In a consumer protection approach, in contrast, it is claimed that individuals may not have the time or knowledge to make informed choices, or may not have reasonable alternatives available.
