Agreed. Once privacy becomes the driving issue of social networks, either Facebook, G+, or the next evolution, will offer users what they consider to be proper security/privacy. Although we can be seen as the products and not consumers of Facebook, if we are being harvested for social data, we will require proper care and growth to deliver a good product.
I think, since this is so new, there is no clear understanding of what the "correct" privacy controls are. That is why I love the fact that G+ exists. Competition will help solve this problem.
