In 2010, Yahoo! chose to let users sign in to their services via Facebook and Google, a move made under then CEO Carol Bartz. But the web giant is currently under new management, and there’s all this ad money waiting somewhere. Why, Marissa Mayer may be asking, should they share user data with anyone? Can’t Yahoo mine this data and profit from it themselves? So to offer “the best personalized experience to everyone”, there will be no more signing onto the service through Google or Facebook. “The change to the Tourney Pick’Em sign-in process began on Monday,” says a Yahoo spokeswoman, “users can still access other services with Google or Facebook IDs.”
Soon this changes will come to all Yahoo services including Flickr and Tumblr.
