Three Democratic Senators held a press conference last week to criticize Facebook’s new information policy, which allows Facebook to share more information to third parties without user’s consent. The new privacy setting requires users to opt-out, rather than opt-in, to have their information shared with third parties.
Facebook responded by saying that user information is only shared with "pre-approved" third party websites, not the entire world at large. There does not appear to be specific criteria for how or why another website is approved to receive user information.
The Senators indicated they are now trying to get the Federal Trade Commission involved, and hoping it will result in stricter rules for disclosure of sharing information.
