Yes, same outrage: it’s most of what I’ve worked on for twenty years. But “you’re already surveilled” isn’t a defense of Flock, it’s an argument for less surveillance everywhere.

Volume isn’t the distinction that matters, who holds the data and what is possible as a result is. Meta can sell my movements to an advertiser. It can’t pull me over, detain me unjustly, or hand my neighbor over to ICE. With Flock, police aren’t a downstream buyer; they’re the direct customer.

And “you already gave it away” is no longer good law. Chatrie v. United States (2026): Chatrie had opted into Google Location History, and the Court still held that disclosure to a third party doesn’t forfeit your Fourth Amendment interest.

Worth noting where we started, though. Two comments ago there was no plausible connection between public roads and privacy. Now there’s one, it’s just smaller than Meta’s. I'm really glad you have had this anparently eye opening moment here on HN.
