>A simple counterargument would be that cellphones do not consume a public resource, unlike the way taxis consume road space, so there is no reason to share said data with the government and consequently the public. That argument would be incorrect, since all cell phones run over a public resource: the airwaves. These airwaves are licensed by the FCC licenses to private companies, but (in theory at least) the public retains ownership of those airwaves.
