Pretty sure they’re typically publicly owned. Maybe some places lease them. Couldn’t find a national survey, but here’s at least one example of a county that bought some machines and a service contract.
Maybe a car fleet is a good example. Ford designs and builds the cars. Counties buy them, and often buy service and maintenance contracts to keep them running. The counties still own the cars.
I suppose counties could receive the source code, have it audited, and then compile and load it themselves.
Fucking cool, and also remember to leave your phone at home, or at least on airplane mode.
