In Netherlands: not just the government, also pretty much every major business and even Universities (Groningen comes to mind). And not just Google, but also Microsoft (Teams, Outlook, etc).
I've often wondered whether that is the real main reason why so little innovation comes out of Europe vs the US: everything of economic, academic and geopolitical importance in Europe is streamed straight to the US and the sender is paying for the service of having valuable information leakable.
Groningen is an outlier in using Google Workspace for email iirc. Most of the Dutch universities I came into contact with (including the one I used to attend) were deep into on-prem Exchange, with some moving to O365.
