Since the article contained some private Dutch governmental documents, I think you are correct to state the last case (some non-public). Though if the are public, reselling them (or making profit as a side business) without referring to the original document is problematic at best, illegal at worst. There are plenty of sites who reference or even quote published documents from the overheid.nl (goverment) websites and make profit from them, but not by copying them without reference. Though they all serve some legitimate purpose and you can actually download them instead of having to click though quizzes and other annoying things in the hope you will click one advertisement.
