Absolutely no disagreement from me on anything you wrote here and sorry if I came across as diminishing the article you submitted. I was not, I was merely evoking a common thread in many thousands of HN articles where a great story is posted that is based off of a primary source, but somebody always asks for the link to the primary source. I think derived articles are not always "blog spam", and can usually offer interesting and unique commentary and insights above and beyond what's more or less a press release. Your submission definitely rises to that level. But it's irritating that the actual source of the news got killed (regardless of who submitted it).

In this case the opposite happened, but the primary source was killed. I know this is all a bit meta for HN, but even more meta, I'm finding it more and more frustrating to submit things as so many sites are now set to auto-kill.

Sorry if such and such news site is considered too biased, but it may be the only or primary source for a story. The autokill is also surprisingly biased in and of itself. For example, an article posted from Android Police will get killed, while an article MacRumors won't.
