This thread is a great example of the problems Microsoft faces among HNers, but I don't think the general public has such a blatant bias against Microsoft.
For instance, this topic was submitted 9 hours ago, has 128 points and is on the front page. It also has a false title.The title asserts that "Microsoft has lost $9 billion on Bing". However, the CNN article doesn't have this title. The article says that Microsoft "has lost $5.5 billion on Bing since the search service launched in June 2009".
Now, HN moderators often heavy-handedly change submission titles on the grounds that the title violates some obscure HN rule (like for example, the rule that "X ways to optimize your app" is inappropriate)
In this case, we have a much more blatant rule violation - changing the original title of the story and substituting it with a false assertion. Yet, none of the moderators have changed the title of this story.
