Hate your free service? Go tweet yourself
Not to single Facebook out, but its history perfectly illustrates the progression of a free service - from partner-in-symbiosis with users, to bloodsucking parasite. An Electronic Frontier Foundation timeline and a Matt McKeon visualization, both from 2010, demonstrate the speed with which Facebook's privacy policies eroded as the service got larger and desired more user information to sell to advertisers. Locking users in is a profitable strategy. Recruiting millions of users and selling them to advertisers has garnered Google a projected 33 percent share of the global online advertising market.
