"there are no plans"
this is either a lie (well, until such plans are leaked they can say what they will), and as a half-truth as "no plans" (well, specific plans), this is another lie, i.e. they clearly indicate they're cooking something. So, there is a very precise plan to harvest more data, sure. It's just unfortunate (for facebook) that whatever talks they hold, they're in the limelight and any facebook story gets picked up by media.
All that said, I don't think they should fret, after all, a huge majority of their users WILL opt in to just about anything facebook asks them to.
