Instead of making a fuss, have you considered taking another look at the video page? It includes a summary that helps show why those technical facts are actually relevant in the context of German society, and hints at how those things came to happen. I would normally not bother with a comment, but this time I'm genuinely curious as to how someone might have missed scrolling down to see the summary.

(edit: the fussy bit, where the poster complains about downvotes, has been edited out. I'm leaving my comment the way it is.)
