personally, i doubt this to be true. the voting masses are by and large not that smart on issues like this. granting access to personal data in order to receive promotional information has been accepted and liked by a large percentage of the masses. if not liked, then tolerated. if not tolerated, then willfully ignored.

if the argument is to get discounts on retail products/services, then of course the "think of the children" or "but terrorists" will work on them as well.

putting that much decision making in the hands of the voting public is always a scary idea, and never a sure thing.
