The letter was signed by the Electronic Privacy Information Center, the Center for Digital Democracy, Consumer Watchdog, Patient Privacy Rights, U.S. PIRG and the Privacy Rights Clearinghouse.
The groups expressed particular outrage that the policy change would also cover teens. Facebook said that by agreeing to the new policy, users who are younger than 18 "represent" that their parents have also agreed to the terms.
"The amended language involving teens — far from getting affirmative express consent from a responsible adult — attempts to 'deem' that teenagers 'represent' that a parent, who has been given no notice, have consented to give up teens’ private information," the groups wrote. "This is contrary to the Order and FTC’s recognition that teens are a sensitive group, owed extra privacy protections."
Facebook had already been including users' photos and other information in advertisements and paid $20 million to settle a class action lawsuit over the practice. Notifying users of the advertising practice was part of that legal settlement.
In a statement, Facebook emphasized that it is only revising its policy statement and not any of its actual practices.
"As part of this proposed update, we revised our explanation of how things like your name, profile picture and content may be used in connection with ads or commercial content to make it clear that you are granting Facebook permission for this use when you use our services," a company spokeswoman said. "We have not changed our ads practices or policies — we only made things clearer for people who use our service."
