Personally - on at least two occasions, I've been accused of writing code that was specifically written to cause grief/problems with another person, only to have to explain that it was a bug and that their personal test-case isn't the only place where it fails.
* And even if the author did directly accuse MS of cheating, that doesn't mean we can't be more correct and rewrite it to be neutral.
In my personal experience, assuming bad will on another person's part kills all chance of civil discussion and severely hurts your chances of finding more facts, because people are on the defensive. Not to mention how hard it is to remove that sort of egg stain from your face.
that'll be 2¢ please!
