The first link is a mistake. It's supposed to be the thing being discussed here: https://www.hackerneue.com/item?id=45170164.

The 2nd link seems reasonable to me? Why does a study about 25k workers in Denmark (11 occupations, 7k workplaces) not count as evidence? If there was a strong effect to be found globally, it seems likely to be found in Denmark too.

Also, what about the other links? The discussions about the strange accounting and lack of profitability seem like evidence as well.

If anything, this article struck me as well-evidenced.
