So, all they did was privatize their postal service. There will still have a postal service, but run by a private company.
I doubt this will end well, but Denmark is a small country so maybe it will work.
After a year it would be nice to see stats and compare delivery time, lost mail, cost between Dao and the old service,
It was already a corporate entity running it, just one owned by both Swedish and Denmark governments

It is still the 2nd largest company in Sweden. They just gave up on Denmarks mail contract after the vast majority of people stopped sending mail and now another company is taking over the much smaller operation.
