My slightly pessimistic view is that the ones with resources would be able to keep their privacy and use that to their advantage, while the less fortunate would not. Popular opinion might change, but as we've seen laws can change much more quickly, and even things that most people would consider normal could become a punishable offense. At that point, for the people who already have the data on their lives out there, it will be too late to do anything about it, while the people who have been smart enough to live "perfectly normal" lives with the correct political and religious views, or those who can hire people to cover their tracks, will be better off.
