This isn't about censorship it's about civil rights, and government agencies circumventing privacy laws by claiming that any data they can purchase is publicly available and therefore not subject to those laws.

The report notes: “The government would never have been permitted to compel billions of people to carry location tracking devices on their persons at all times, to log and track most of their social interactions, or to keep flawless records of all their reading habits. Yet smartphones, connected cars, web tracking technologies, the Internet of Things, and other innovations have had this effect without government participation.”

The government must appreciate that all of this unfettered access can quickly increase its own power “to peer into private lives to levels that may exceed our constitutional traditions or other social expectations,” the advisers say, even if it can't blind itself to the fact that all this information exists and is readily sold for a buck.
