@rasmus91 @Gurre I feel like Denmark are doing a lot of things right in general.
As far as I know (correct me if I am wrong), Denmark decided to make e-mail encryption mandatory, and then relied on this existing decentralized technology for sensitive communication from the government, for example.
What did Sweden do? Well, we now have private companies like Kivra providing "secure inboxes" for people. Completely centralized, and with some proprietary (although open) protocol.
