You needn't use your real name, of course, but for HN to be a community, users need some identity for others to relate to. Otherwise we may as well have no usernames and no community, and that would be a different kind of forum. https://hn.algolia.com/?sort=byDate&dateRange=all&type=comme...
Maybe what they're doing works for them for some other reason.
EDIT: though the higher relative numbers of severe cases and deaths might indicate they don't know how many cases they really have.
The cumulative number of patients admitted to intensive care is 278, and since we had 510 intensive care before the start of the pandemic, that is not a problem at all.
Unless you have reason to believe that the ratio of patients requiring intensive care somehow has decreased radically during the course of the pandemic, the growth of cases is most certainly not exponential.
Looking at urbanization:
Denmark: 87.5% [0]
Sweden: 87.4% [1]
Another statistic is Copenhagen Metropolitan area compared to Stockholm, which both is about 2.5 million. Though Copenhagen jumps to 4 million if you go by the Öresund region including parts of Sweden. [2]

The epidemic is still growing fast though and since some countries are naturally lagging behind others, the effectiveness of measures will only be seen in the aftermath.
