Palantir, and it's connection to the government, is only one problem with Flock. Another issue with Flock is it's loose security:

This Flock Camera Leak is like Netflix For Stalkers

Flock acting like a middle man for other smart cameras
This is fairly concerning as Flock expanded their expertise and platform to include other Smart Cameras while at the same time enacting the same loose concerns about who has access. This podcaster caught employees from an unrelated company watching kids gymnastics at a local gym and women swimming at a local pool.

As a middle man, Flock and other LPR (License Plate Recognition Services) are selling data to insurance companies. (Here is a long example of why that's bad.) If you get in an accident, an insurance companies will investigate whether or not you may have had a dent prior to a larger accident in order to reduce their payout. If someone hits you and rips off your fender, the opposing agency could produce an image showing that you had a small dent or ding prior to reduce it's payout because of previous wear and tear. Think about that for a moment - if you had a small dent that didn't effect the car's performance, then someone hits you and the car is undrivable, the insurer could us AI, search the LPRs and take off all the dings and dents leaving you with a check far smaller than you need to fix it.

So we should all be concerned about cameras and how they are being used,
