Recently, Facebook changed its terms of service and it's caused such an uproar, even the mainstream media is covering it. Thankfully, Carlos Longino over at Techdirt cuts through the hyperbole to explain what's really going on:
Some Facebook users are in an uproar after the site changed its terms of service to say that it retains a license to users' content after they delete their account. As the company's founder, Mark Zuckerberg, explains, this change simply clarifies the point that actions on Facebook can create two copies of content. He says that when users add a friend or send a message, for instance, it generates two copies of the action: one for the user on each side. So say a user sends a message to a friend, then later deletes their account; the new TOS language clarifies that Facebook doesn't have to delete that message from their friend's inbox.
Privacy mongers, have no fear. Lately, Facebook has been littered with memes that ultimately drove MySpace to its current irrelevance.
