Now let's ask Judge Roberts, "is this an unlimited right?"
Agreed. The Constitution is protecting that which is specifically mine. Phone records generated by my activity during the use of a publicly offered service don't belong to me; they belong to the entity providing the service.
Just like retailers who share my online purchasing habits in order to more effectively market to my tastes, they are dealing with the results of my activities. In no case am I under the illusion that my activities in the public marketplace are protected or private.
