White papers are shit written by marketing people who try to make their little ad sound like something academic. In truth these white papers are in equal parts misunderstandings, wrong and full of useless fluff. They are AI slop, often completely without any AI involvement.
If someone is serious about the content, they call it a documentation, reference or datasheet.
Those aren’t white papers. They are scientific papers.
White papers are written by companies as a marketing tool. The first two papers you linked above are written by universities and the last one by a research-focussed non-profit.
As per Wikipedia:

It’s a marketing presentation masquerading as a fake scientific paper.
