Interestingly, browsing to your example link with uBlock Origin blocking all javascript by default I get a page that looks like indexes to articles. Clicking on one gives me what appears to be the full article. As I can not read German, I pasted part of the text into google translate, and yes, it does appear to be the full article text.
So for at least that site, it appears that all of the 'protection' is provided by javascript, and if one does not allow the javascript to execute, one receives the article content. There also does not look to be much in the way of ads with the javascript blocked as well.
