Microsoft does have a separate government- specific subscription with slightly different features, and that may be part of it.
The most annoying part of the government system is that it only allows one MS account to be logged in on a mobile device, so for people with accounts in multiple municipalities (e.g. county officials needing access to permitting data from several cities), they need a different device for each system.
