This piece of investigative journalism has been posted on HN some 9 months ago. I'm reposting it now because a) it's a really thoroughly researched article, and b) it's presented in an interesting and engaging way (edit: on desktop at least; I haven't checked how it looks on mobile).
So, dear HN: trust me when I say it's worth spending some of your time on this one even if you're not interested in the subject matter itself
