Yep in the article it says ..the National Library .. has the single largest digital collection of Norwegian books, newspapers, web pages .. it is entitled to receive copies of every published book and broadcasted content. Its legal deposit mandate in this area extended beyond books, as it was duty-bound to collect and preserve all of Norway’s cultural heritage .. an agreement with Norwegian newspapers permitted LLM training on copyrighted content.

So yeah they seem to have proprietary data...
> proprietary data
It is just copyrighted data, that is harder to get a hold of. All the copies are available to anyone to use if they just read it. Copyright makes other uses complicated. I wonder if the whole Creative commons debate was a mistake, you can never fix copyright in a digital world.
