Facebook, Inc., launched a program called “Bea-con” that automatically updated the profiles of users on Facebook’s social networking site when those users had any activity on Beacon “partner” sites. For example, one partner site was Blockbuster.com. When a user rented or purchased a movie through Blockbuster.com, the user’s Facebook profile would be updated to share the purchase. The Beacon program was set up as a default setting, so users never consented to the program, but they could opt out. What are the ethical implications of an opt- in program versus an opt- out program in social media?
