Interesting historical material is always welcome on Hacker News. It's true that this story includes the words "Nazi" and "Gestapo" in its title; but not all such titles point to uninteresting flamebait, only most of them. Here we're interested in the exceptions to things.
I meant it more as a wry aside to keep the readers of tedious moderation comments mildly entertained, but you're right: it's awfully hard to do that and not cross over into being inflammatory to some readers.
It's pointless to ask that question (in any forum really), unless you love downvotes. If you want to contribute something, post about why think it shouldn't be, with references to the HN guidelines that you think backs up your case.
Same answer about that one, actually: it's much more interesting than most articles with that theme. On HN we judge things article by article. That's the only way to optimize for curiosity.
