Math is exactly correct. Law enforcement (in the US) must get a warrant for a telecom company to release privacy location tracking and call record info. The fact in this case that it was obtained without a warrant is really a failure of the telecom company as a first gate stop. All they had to say was "Not without a warrant." So whoever authorized that without a warrant, and whatever telecom company it was, they need to be included in said lawsuit.
I spent 10 years in the telecom business and know first hand what it takes to hand over user data to law enforcement. Also keep in mind this data is used for tracking missing persons. So effectively NOTHING has changed. All SCOTUS did was restate the 4th Amendment that it takes a warrant. Waste of time for SCOTUS. And regarding the fingerprint/unlock issue, if they have a warrant, it's just like entering your home and searching all of its contents: you lost ALL your rights to privacy by the signature of a judge.
