Imagine a country investing billions of its taxpayers money over several generations in administrative data of extremely high quality only to give it away for free to random foreign researchers. A country is supposed to serve its citizens first, and foreigners second. Not the other way around.
I can't tell if this is sarcasm or not. On the off chance that it is not sarcasm, the service provided to its citizens is to permit the highest quality research on questions of national interest not just the best research only a swede or norwegian is capable of.
