Plain and simple, the gathering and control of knowledge/information is something that should be as decentralized as possible, particularly where government is concerned. The control of information is power. Centralizing it closer into the depths of the white house is a potential to withhold information and manipulate it. It's taking the process further from the public eye. Saying one needs evidence to to accuse one of having ulterior motives is malign to the fact that people should seek to abate that possibility as much as possible. Allowing moves such as these to continue, accumulating power where it does not belong, is not in our best interest.
You can ride off each and every little thing as being inconsequential, but what people scarcely realize, until it's too late, is that these things accumulate until they contribute to a much greater problem. This fatal error in judgment repeats itself continually, and is embedded in many of the problems we have today. Every issue has a macro and micro significance. What may seem insignificant on the small scale may very well have much greater implications when one looks at the big picture. Inherently, this means things can be both insignificant and significant at the same time.
