I am certain that many people in government would agree with you - they would LOVE to be able to hide what they are doing and not be held accountable for decisions they make (or don't make). We need more public disclosures, not less, imo.

This website didn't make them public, they just gave others a way to access them - once something is public, and in control of others, it is impossible to make them 'un-public' without violating the 1st amendment.
