The depressing answer is that if the changes are made official, there's nothing users can do directly, since according to the A.S.M.P. 'Facebook has specifically removed the language from their TOS that allows you to limit how your likeness, information, and content are associated with brands, commercial uses, or sponsored posts. They have also removed the clause that makes them subject to the privacy limits set in place by you on your profile.
'The A.S.M.P. suggests that members 'become informed', 'spread the word', and 'call for action' from other professional organizations with whom they work to 'ensure fair and respectful treatment of users by online services like Facebook and Instagram.'
