More along the lines of "if you want to give us feedback about your transaction with this site, sign up here" I think.
Google has plenty of lawyers all over the world, and if it doesn't pass EU legal muster, then they won't roll it out in the EU. So far anyway, there's no promise of better SERPs whether you have it or don't, and nobody's being forced into it. But from what I've seen, they're not having too much trouble getting US vendors to sign up.
