I agree that corporate v. state actions are definitely important to distinguish, but in the US, corporate malfeasance is left untouched and unpunished by the state so often that the line between the two is pretty damn blurry.

*Also, thinking on it a bit more, it's not like the surveillance is inaccessible to the state, either. If cops subpoena the footage, or even just ask for it, they'll almost certainly get it from a corporation. So this is more so just a layer of obfuscation from direct state surveillance, with the added nuisance of harassing people for standing on the sidewalk for "too long".
