This data all stored in OpenStreetMap via DeFlock and other apps. One thing that should be said is that anyone can plot a camera via these apps whether or not one is actually there or not. I know that OSM community has been dealing with a lot Flock related vandalism because of these apps.
The full export of OSM is about 2TB but the US is only around 100GB even if you go to insane levels. It's disproportionately large because there are a hell of a lot of OSM-ers in the US ;-)
Anyway what we should do is keep a few clean snapshots of the US as a backup, on hosting safely outside the US - or US-owned companies.
