Schneier's argument is that openness shouldn't work both ways:

Privacy has to be viewed in the context of relative power. For example, the government has a lot more power than the people. So privacy for the government increases their power and increases the power imbalance between government and the people; it decreases liberty ... Privacy for the people increases their power. It also increases liberty, because it reduces the power imbalance between government and the people
