Is this just another Facebook hoax?

"Friday, Facebook will become owner of the publishing rights of ALL your private photos. You need to make a simple change: go to 'account', 'account settings', 'facebook Ads'(along the top), then go to 'ads shown by third parties', choose 'NO ONE' then SAVE. 2 minutes' job. & please Share share share."

Someone posted this message on my wall today. I know Facebook is notorious for changing things without telling users, but it seems a little weird to me. The setting this message tells you to change only involves Facebook plugins on third-party sites, and it's set to friends-only by default. I can't find anything about Facebook taking publishing rights for users' photos from them aside from the clause in the Terms of Service that gives them permission to display the content you upload on their site. Did I completely miss the news, or do my friends need to be smacked with a clue-by-four?
