I think this is officially the sign of the reddit-ization of Hacker News. Pathetic.
"On Topic: ... anything that gratifies one's intellectual curiosity"
I agree with you. This submission isn't of the type I come to Hacker News to view.
On similar sites, the original post would have never made it to the front page and the comments on both would have been only about astroturfing and Microsoft hatred. ...Which is why I don't comment or waste time reading the comments on those similar sites.
Whenever I see the words "special interests", I immediately want to know which special interests in particular you're complaining about. The words (rightly) have a bad connotation, but I don't often see a lot of agreement about which specific interests are causing trouble.
