Obviously I can't speak for other people, but since you asked:
I'm an OS X user, and before that I was a Linux/Unix user. I'm not really familiar with Microsoft products (especially recent ones). When some cool new tech gets announced, I'm interested by default.
I have nothing against hearing about stuff from "foreign ecosystems", on the contrary. I was an active member on Channel 9 back in the Scobleizer days, and I loved hearing about the interesting things you guys had been working on.
I didn't catch the Nokia article today, but chances are it wouldn't have caught my eye even if it had been among the top ten on the front page. First, it's not actually interesting on a technical level. Second, a lot of us here on HN speculated what MS was doing when you positioned that trojan CEO at Nokia, and then of course it turned out to be true. Not that there is anything wrong with it per se, but I don't see how that dishonest-yet-obvious takeover puts MS in a position to offer anything interesting that it couldn't offer before. The Nokia name accomplishes very little in this case.
It's true that there can be some group hate on HN, however I don't see a lot of it projected at MS - at least not beyond the usual background noise. We as a community are way more hostile towards certain programming languages and startups. Sure, every Apple thread, every MS thread, every time something from 37signals comes up, there are disgruntled people. But enough to single out MS hatred specifically? I don't think so. Disinterest is the more likely culprit.
