I'd move that a level up and say until they see concrete anything.

All of the privacy rhetoric (I realize that sounds dismissive, it's not supposed to) is based on either philosophical notions or slippery slopes. "Something bad might happen to you in the future!"

It makes for effective fundraising but poor impact on policy.. especially when the groups behind most of the privacy erosion like the Googles and Facebooks of the world provide an actual product people like.
