From Alito's dissent in Chatrie: Good. Apply this to all forms of digital surveillance.

CHATRIE v. UNITED STATES
ALITO, J., dissenting
More broadly, where does the boundary between Carpenter and the third-party doctrine lie after today? Carpenter gave "courts and law enforcement officers no indication how to determine whether any particular category of information falls" on the Carpenter or Miller side of the line, and today's decision does no better. Carpenter, 585 U. S., at 340 (Kennedy, J., dissenting). Do the police need a warrant to obtain a person's Amazon purchase history? What about a person's Google search history or Venmo transaction log?
Those kinds of information fall squarely within the third-party doctrine, and today's holding about "cell phone location information" does not ostensibly disturb that fact.
Ante, at 29 (internal quotation marks omitted). At the same time, those data can paint a similarly detailed picture of a person's private life, and law enforcement had no easy way to obtain this information in "an earlier age.' " Ante, at 17.
If the Court maintains its unwillingness to engage with such "line-drawing questions," ante, at 21, n. 9, Carpenter's warrant requirement might soon come for all forms of digital surveillance.
