Pulled from IMDB, Morgan Freeman as Lucius Fox voices the consternation perfectly:

> Batman: [seeing the wall of monitors for the first time at the Applied Sciences division in Wayne Enterprises] Beautiful, isn't it?

> Lucius Fox: Beautiful... unethical... dangerous. You've turned every cellphone in Gotham into a microphone.

> Batman: And a high-frequency generator-receiver.

> Lucius Fox: You took my sonar concept and applied it to every phone in the city. With half the city feeding you sonar, you can image all of Gotham. This is wrong.

> Batman: I've gotta find this man, Lucius.

> Lucius Fox: At what cost?

> Batman: The database is null-key encrypted. It can only be accessed by one person.

> Lucius Fox: This is too much power for one person.

> Batman: That's why I gave it to you. Only you can use it.

> Lucius Fox: Spying on 30 million people isn't part of my job description.

That system is nothing compared to the geolocation databases curated by Apple and Google, with GPS sensors combined with Wi-Fi wardriving, IMEI tracking, cell tower handoffs, and the rest of the insane amount of telemetry they collect collect in real time. And that’s before even considering BLE and the Find My network. Imagine the “God mode” dashboards they could have in Cupertino (or more likely, in Mountain View).

Lmao did they really say it's null-key encrypted?

Unfortunately a very realistic depiction of how many of the brands advertising their security the strongest often have the most ridiculously broken security (flock)
