It is illegal to modify a scanner that is already blocked. I am not going to cite laws and rules to you. You seem to have been sadly misinformed on the subject or are confusing listening to over the air communications such as ham radios whitch have no reasonable expectation of privacy and cellular communications which do. I hope you are not telling folks to do this becasue it is illegal.
Now, back to that reference. That is a different subject altogether. LE is using cell signal with the help of phone companies to track to a device. I disagree with the ruling. But if you notice it does not give LE the authority to interceptvoice communications unless they have a warrant. Next time do more research and understand the difference between a sginal and geolocation and voice interception of cell phone signals.
